thx! I've read some from the manual and understand some things better now... for example the pressure hull damage from the cruiser fire

leading to unstoppable flooding and sinking unstoppable. Am I correct to think that the engine room pressure hull was completly destroyed and therefore not repairable (in the priority list)?
one more thing: if I order to man aa or deck gun, will the crew actually man these stations on their own or do i have to move them there? I had the feeling in TMO that they were not manned on their own.
