Package folder? Sorry, I don’t understand what you mean.
If I try to start stand-alone game from anywhere but Steam, Steam overlay does not show up and subsystem does not seem to work at all. I have to start game through Steam client to have subsystem work.
There seems to be another problem that might be related. After I disconnect from host and destroy session on client, I can reconnect to same host. However, after about one minute, I get just thrown out of game. Could this be related? Or is this something else like garbage collector not unregistering first connection or something?
