I just completely reinstall my server (thank you valve)
I took the opportunity to test the script and the bug is still present when I disabled all my scripts in SourceMod and EventScript
I said that my server runs on Windows (there are not many windows css server or can be of the fact that we are to have this problem 3)
I'm running various servers on windows and after update i don't have time to check but i think is runing fine.
