Hey, I'm unable to reproduce this on a different project and I won't be able to mail you my actual project. That said, I do get
"Core Resources : Info - Blank IdReference found - could be that the project is corrupt." when compiling. Haven't been able to get rid of it for a while (from before getting GMLive) but it hasn't appeared to affect me in any way, until now. Got any tips for it beyond "try the GM forums"?
