I realize this problem has already been mentioned but now it is probably affecting scale selected for your interiors. i am unable to change my interior layouts size and the bridge style. I had had a problem with the game crashing every time I attempted to visit my crew deck or engineering deck, but apparently they fixed that problem. but now that I have the ability to actually enjoy my interiors i do not have the ability to customize the layout. not to say that I can't do it. It just does not take affect.
this is a very annoying bug and needs to be fixed.
PS:it would also be nice to be able to have the classic bridge style (AKA the galaxy class bridge) with my galaxy class. that's just a nitpick of course.
Hm, better post your computer specs, beacuse I haven't heard, or run accross, that problem myself. Maybe it's something specific that you are using on your machine? Also, did you try a force verify on your STO files?
Also, the original Galaxy bridge is there, available in the C-Store (under Federation Bridge Pack: Galaxy Variants)!
