I've had this problem before and it drives me crazy. I've been here since 2011 and have NEVER been able to make a map because every single time I try, once I'm ALMOST DONE, it'll crash and then the game will nOt reopen. I REALLY don't want to delete and reinstall the game again because I worked really really hard on this map and don't want to lose it. I've never been able to make a map before because of this issue so I would really like to know why it's doing this. It isn't the computer because again, I've been here since 2011 and have tried it on at least three different computers. I have no idea why it does this because I was literally working on it all day yesterday, for literal hours, with no problems. But then while adding some trees, it crashed and now the entire game won't reopen. The same thing happened the last time I tried: was working on it all day then crashed when adding trees. Please help
