Project crash

I have the following BP hierarchy.

Spells >> Buffs (child of spell)>>> every buff i created.(childs of buff)

Whenever i start the project and open one of those, it will crash.

If i open something else first, lets say some AI task, and then i open a spell, buff or any child it will not crash this way.

Crash report

I have a backup of buff that is close to the one that crashs, but it has a deleted variable still in it, and cuz of this it fails to compile. If i replace the current buff with this one, it will not crash. but if i then fix it, and thus it compiles, then it will crash the next time i start the project like the other ones. i really don’t know if buff or spell is corrupted, or is something else. and i don’t know how to use the log to find the problem.

i used the backup, it now works but, if i make any change in the buff blueprint, it will crash the next time i start the project.

link text Another crash report, after i deleted 3 bps related to the one that crashs. It is still crashing, but at least now the log looks interesting.

Allready fixed. /close
