connecting via WolfRAT crashes game

[GeRo-]

Hey guys,

I'm trying to make wolfrat working on my PC whilst I host the game.
I'm able to connect to the server via original RAT.exe delivered with the game but I wanna use more user-friendly version.
So I downloaded wolfRAT from this forum.
Then I host the game from JOTR game, I'm able to connect via wolfrat for literally 1 second and then game closes with no error displayed.
I run everything as admin, I used RAT port 44555 and added both JO and wolfrat applications into windows firewall rules. Also I need to mention I'm trying to make this "Serve and play" which is the option I choose from the game.

Any ideas how to make this work?
