I build a bulkhead, but now my base flood!

[Hassink]

My base had 9 integrity, and it is not very big yet. I decided to build a bulkhead in the corridor to my Moonpool, just to see how it looks. You can see it in this screenshot:

This caused my base to suddenly flood, and the only way to stop it is to close the bulkhead from the Moonpool side (closing it from the other side does not work). This restores integrity and starts the draining for the rest of my base, Moonpool stays flooded.

Am I doing something completely wrong in bulkhead construction? Or is this some weird bug?

Any tips to get my base back to normal are also welcome. I tried removing the bulkhead but this just floods my base again. Cant find any breaches either (though Im not entirely ure what a breach would look like...)

[TheGraveDigger]

is there any breaches in your moonpool?

[Hassink]

None that I can find... But why would they even appear in the first place?

it's possible you did something else to damage it, like you ran a vehicle into it, or maybe there are some tiger plants nearby.

The bulkheads should actually help you isolate where ever the puncture is. The side without the puncture should drain when the door is closed.

The damage itself will look like a small vertical crack. You should see air bubbles coming from the puncture. As for why there might be a hole, the causes are:
- Accidentally hit the base with the sub
- Accidentally hit the base with the Prawn's arms
- Tiger Plant fired and its projectile hit the base

If you're certain it wasn't the first two, look carefully in the area for Tiger Plants. If you want to get rid of them, they can be killed with 3 attacks from the thermal knife.

From the looks he's in safe shallows so there should be no Tigerplants.

Do note that the moonpool eats a whooping -5 to integrity. I would suggest you deconstruct the moonpool ,check for integrity and then construct it again.

Could be that you get to or below breaching point before you constructed the bulkhead and the game registered the integrity fail thus flooding while technicaly you were fine.
Subnautica do has it's slight "brainiac" moments sometimes xD

Might've had a Crashfish hit your base or something. Keep the bulkhead in your base and keep it close so the whole base doesn't flood. The breach will be located in the flooded area which helps isolate the problem.

My seamoth was in the Moonpool when the leak started.

There are no predators nearby (just some gasopods floating around).

And as stated earlier, the integrity was always okay. The bulkhead was placed for decoration, not necessity.

I think I'll be spending some time later today to find a way to drain it all. Worst case scenario I'll have to rebuild the moonpool section entirely, but the seamoth is still in there....maybe I can just rebuild the corridor.

It'll drain automatically when you repair the breach. You shouldn't have to deconstruct and/or rebuild anything unless your game is bugged.

Construction can only cause damage if it's something that reduces integrity, and your integrity is already low enough that the construction puts it into negative numbers. Bulkheads increase structural integrity and have no other means of damaging things, so as others are saying, something else probably damaged your base around the same time you built the bulkhead, and it's just that accident of timing that made you think the bulkhead did it.

Find the crack, repair it, and the base will drain itself. Then go outside and look for anything in the vicinity of the effected module that could've damaged it. Empty crashfish nest, floater-propelled rock, tigerplant, etc.

Should I look for the breach on the inside, or the outside of my base?

[RCMidas]

Inside. I advise letting the whole place flood so that it is nice and obvious where the bubbling breach is.

It should be easier to see from the inside. The damage will always be on the walls (never ceiling/floor) and about at chest level. If you've already been to the Aurora, the breaches will look similar to the ones you had to repair in the drive room..

[Hassink]

Well, looks like you guys are right. Turns out there was a breach in my moonpool. Saw it right away when I entered through the floor.

I blame a crashfish, I remember avoiding one earlier....

Thanks for the help!
