the fab room has duct blocks that are connected to the shuttle area which is not able to be drained with the lever before you enter the shuttle, I think its connected to the outside water and so what ends up happening when the fab room gets flooded and the ducts open to let the water out but since the shuttle bay isnt water tight keeps filling with water from the outside and the ducts never close leading to the room the being permantly flooded the rest of the mission\campaign

I'll investigate that,
Thanks for the bug report!

@Sebastion
Duct blocks have been moved, and now they are not connected with hangar.

The engines of the shuttle might need to be moved because the engines cause harm to the player when passing between the shuttle and the main ship, especially worse with neurotrauma installed

oxygen generator on minisub is not repairable. Everyone just too short to interact with it

@Seabastion
That red circle has been moved to the outside, previously it was in the middle of the engine room
@ТЕРМОЯДЕРНОЕ УЕБ
fixed
