Hi all, I began to start facing strange crash which I can't understand why it happens.

Spoiler!

Even it happen on map change when I changed the map via webadmin when no players pressed join.
One thing that I noticed is that it doesn't crash when turning off the Map Vote option in KFMapVoteV2Handler. Any ideas, maybe someone had the same problem?
EDIT : nah only few maps more works fine...
EDIT2: nevermind found the problem and fixed(in 3 days lol).
