https://github.com/rwmt/Multiplayer/releases here i got the MP from, this has a later date than the steam version.
The desycnt just happends, there is no error message...
Or does it save logs somewhere without saying error?

Woulr be totally awesome to find a way to use your mod in MP. Im not into placing stuff on the floor or lowering temperatures of a whole room. I have a fridge, i dont freeze my whole room in RL ^^

will look for stuff, gonna post it here if i can get a log for you :)
If you know where it is, just tell me.
