Tried every possible fix and solution, nothing makes it remotely playable in MP.
Crashing, disconnects, weird workarounds that are mandatory.
That is if you even get this POS to run in the first place, good luck.
A great game made terrible, thanks for that.
At least tag the MP as beta, or even alpha. Tag the whole game as a beta.
Don't advertise it as having a MP function when you can even get that to work properly.
Tried this a few YEARS ago, thought it would have improved by now, but i guess not.
The only thing that worked good so far was the refund mechanic in steam.
