If you’re stuck trying to open the final Angel Comb in Subnautica 2, you’re definitely not the only one. A huge number of players have been confused by the closed flowers, hidden cave objectives, and strange progression bugs tied to the Angel Comb questline.
The good news is that most players are not actually softlocked. In most cases, the Angel Comb flowers won’t open because you still need to clear additional infection nodes hidden deeper in the biome.
Here’s what’s really happening and how to fix the Subnautica 2 Angel Comb bug.
Right now, this is one of the most common progression issues players are running into during Early Access. Many players reach the final Angel Comb, try using the Feedback Resonator on the nearby flowers, and assume the mechanic is completely broken because nothing reacts or opens. However, the game currently hides an important objective deeper inside the infection zone that many people simply miss during exploration.
The confusing part is that the game hints at “healing the children” without clearly explaining where those hidden juvenile infection areas actually are. As a result, players often spend a long time shooting closed flowers, thinking the Feedback Resonator upgrade is bugged or the Heat Tower progression has failed.
In reality, most cases are solved by finding the deeper cave infection sites connected to the branching roots nearby. Once those hidden Bloom Cankers are cleared, the final flowers usually open correctly and the Angel Comb progression continues normally.
Why the Angel Comb Flowers Won’t Open in Subnautica 2
The final Angel Comb progression is tied to multiple Bloom Canker and juvenile infection areas scattered along the infection roots.
Many players reach the adult Angel Comb, try shooting the nearby flowers with the Feedback Resonator, and assume the mechanic is bugged because nothing happens. However, those flowers remain permanently closed until the hidden “children” infection sites are cleansed first.
This is why so many players searching for:
- Subnautica 2 Angel Comb not opening
- Angel Comb flower bug
- Bloom Canker not opening
- Feedback Resonator not working
- Heat Tower progression issue
all end up running into the exact same problem.
How to Open the Final Angel Comb
To properly unlock the final Angel Comb sequence, you need to follow the infection roots farther north through the biome.
Eventually, one of the branches leads toward a wreck area with a deeper underwater cave system. Inside that cave are additional Bloom Cankers or juvenile Angel Comb infection sites that must be cleared before the final flowers become vulnerable.
A lot of players get stuck here because the game never clearly marks the hidden cave location. Instead, it only gives vague dialogue hints about “healing the children,” which leaves many players wandering around the main Angel Comb area shooting flowers that cannot actually be damaged yet.
Once those hidden infection areas are destroyed:
- the nearby flowers finally open
- the Feedback Resonator starts working correctly
- the adult Angel Comb progression continues normally
Several players originally believed the Angel Comb flowers were bugged because the closed nodes completely ignore Resonator attacks until the hidden cave objectives are finished first. This also explains why some players run into Heat Tower progression issues immediately afterward.
If the flowers still refuse to open even after clearing the cave infection sites, try restarting the game or rehosting your multiplayer session, since co-op desync bugs have also been reported during this sequence in Subnautica 2 Early Access.

Do You Need the Feedback Resonator Upgrade?
Yes. Some Angel Comb flowers require the upgraded Feedback Resonator to activate properly.
Even with the upgrade, though, the flowers still stay closed until the hidden juvenile infection sites are completed first. That’s why many players think the Feedback Resonator itself is bugged.
The confusion mainly comes from the fact that the flowers visually look interactive long before the game actually allows you to destroy them. So if you already upgraded the Resonator but nothing is happening, the problem is usually tied to unfinished Bloom Canker progression somewhere else in the biome rather than the tool itself.
Several players also reported getting stuck after reaching the Heat Tower area too early, which can make the progression flow feel even more confusing during this section of Subnautica 2.
Can You Accidentally Bug the Angel Comb Quest?
Unfortunately, yes.
Several players discovered that you can sometimes interact with the final Angel Comb early and receive the adaptation before finishing the intended progression path. When this happens, the nearby flowers may stop responding entirely.
This appears to be an Early Access progression bug rather than intended behavior.
Because of this, some players mistakenly believe they permanently softlocked their save. Thankfully, many cases can still be fixed by revisiting the hidden cave objectives or forcing the area to reload properly.
Multiplayer sessions seem to make the issue even worse, especially when co-op players complete objectives out of order or interact with the Angel Comb at different times.
Fixes Players Have Tried
If the Angel Comb still won’t open after clearing the hidden cave section, these fixes have helped some players:
- fully restarting the game
- rehosting the multiplayer lobby
- leaving the biome and returning later
- re-equipping the Feedback Resonator
- replaying nearby dialogue triggers
- verifying game files on Steam
Multiplayer sessions seem especially prone to desync issues that can break Bloom Canker progression. In some co-op lobbies, players reported the flowers remaining permanently closed even after every infection node had already been destroyed.
Since Subnautica 2 is still in Early Access, progression bugs around the Angel Comb and Bloom Canker systems are still being discovered by the community.
Is the Angel Comb Bugged in Multiplayer?
Possibly. Community reports suggest multiplayer increases the chances of progression bugs, especially when players complete objectives out of order.
Some co-op players reported flowers remaining permanently closed even after every infection node was cleared. Others mentioned the Feedback Resonator suddenly stopping working correctly after one player interacted with the Angel Comb before the rest of the group finished the required Bloom Canker objectives.
The biggest issue appears to be multiplayer desync. In some sessions, the game seems to track progression differently between players, which can cause flowers, infection nodes, or dialogue triggers to behave inconsistently. This is especially common when players split up and complete different parts of the biome separately.
Because Subnautica 2 is still in Early Access, progression issues around the Angel Comb and Heat Tower areas are currently fairly common. Many players across Reddit, Steam forums, and Discord communities have reported similar bugs since launch.
Final Thoughts
The Angel Comb progression path in Subnautica 2 is much more confusing than it first appears. Most players who think the flowers are bugged are actually missing the hidden cave infection area connected to the roots farther north.
The game currently does a poor job explaining where the remaining juvenile infection sites are located, which is why so many players end up stuck shooting closed flowers for long periods of time. Once those hidden Bloom Cankers are cleared, the final Angel Comb sequence usually works correctly.
Still, there are legitimate progression bugs tied to unlocking the adaptation early, especially in multiplayer sessions. If restarting the game, rehosting the lobby, and clearing every hidden Bloom Canker still doesn’t fix the issue, you may simply be dealing with an Early Access bug that requires a future patch from the developers.
