Hi there, as the topic says, if i want to host an multiplayer game, i always getting this error.
I also wounder, why i only have the 1.2.0 version, but on the github projekt is already an 1.2.1 version since 3 months..
i tried to build this addon on my own, but i allways getting an engine error. saying that this isnt a valide gamemode..

I will test if i get this somehow to run, but maybe one of you guys know already an better solution.
