im talking about when the structure is still active, like for axample a residence, it can be serisouly damaged, and have many big holes in it, yet its still active and people still live in it, you cant tell me that they would just leave it as it is, I mean, they wouldnt be able to repair it fully, but they would at least build a rudamentary hull or somthing to keep the air in
and of corse they wouldnt repair during combat situations, they would be down in their shelters, but after the battle they would come out and clean up
