thats possible, but im talking about things like your crew fixing a bulkhead, and a half second later the bulkhead collapses and the whole sub is destroyed.
its missleading

either it can be fixed or it cant, now if it says it can be fixed and shows progress, then when i get it repaired i expect it to work again not blow up.
i remember having systems outright destroyed in SHIII and it was very obvious they were broken.
in this its really not. maybe thats where the problem lies ?
