EDIT: I'm rebuilding the stuff I changed with an earlier version, and it seems to be working so far. Even so, it'd be awesome if someone could help me find out what was wrong in case this happens again.
EDIT 2: Lo and behold... it has returned.
First of all, I have no idea what that means. All I know is that my game crashes whenever it tries to restart the layout, but works perfectly up until then. This started happening when I was re-arranging events on Mario's main movement event sheet into groups, but I don't see how any of it could cause a problem like this...
It's probably not a problem that re-installing would fix, since older versions of the game run fine. If this was Construct's fault, I'm assuming they'd all be affected, right?
Normally, I hate posting caps since my project's getting too big for me to just ask people to look through the whole thing, but this is kind of... a big problem.
Since I've been organizing stuff(which apparently caused the problem in the first place!) it should hopefully be easy to find your way around. Thanks in advance to anyone who tries to help me.
