The game server crashes when passing the last boss.

When using the co-op mode, when the last boss is passed, the game server stops working. I'm using the latest version of srb2, using a KVM VPS server, 1 core, 512 RAM, Ubuntu 18 OS. I run the exe file through wine 3.0 in the screen window. I use the command " screen wine srb2win.exe-dedicated-room 33-password pass &". Perhaps my way of starting the server is not the most correct, and there is a better way. If so, tell me how to run the server correctly on my machine with Ubuntu? Perhaps you need to use additional DLLs or additional parameters at startup, if so, tell me what exactly you need to use? (Translated from Russian, possible misunderstandings)

The problem is no longer relevant. In version 2.2.2, everything works fine for me.
