About saving. It seems my game wasn't saved for some game days (like 5 to 10 days) .
Also I notice that maps and things I hang on the walls disappear. (The history and Math stuff)
I will come back if the problem persists. It might have been just my impression.
Edit: Also, PLEASE solve the thing where you can place random rectangles full of fresh rebar foundation if you right click in a certain way (hard to explain, only happens accidentaly)
(This:)
Rectangles of rebar foundation just appear randomly, I just remember that I right click and fwap, a new random layer of foundation appears, and it overlaps with what I already had going and now I have to demolish and make the whole thing again (the double foundation overlapped inside each other make designated rooms (classrooms, lounges etc.) buggy.
EDIT2: AGAIN. GAAAH, PLEASE, FOR GOD'S LOVE, AN UNDO BUTTON. :(
