It's same with AI or real player fight. How fix that?
I redownload game from site and flush ".onlineboxing3d" folder. Nothing change.

I dont know. I haven't done anything to the game lately.

Now i try run AI-fight, and is WORK!
But shutdowned multiplayer-server, cannot login.

I restarted server, should work now
