Hah, thanks. I've got it like I want now but... It keeps crashing. D= It worked fine for two days, then when I tried to make a new mission, it works while I terraform, etc., but when I try to load a building, it crashes after a few seconds. It's really annoying, because it was, as said, working perfectly fine before.. =\
And how long are your missions (by act and how many objectives in each)?
Edit: I found out what made my game crash! For some reason a building I made was doing it. xD
