Plutonium

Resxt Okay no worries! I figured this might be the case but thought I'd ask to confirm. Thank you!

Yesterday my friends joined my lobby for multiplayer and every time I tried putting us into a server together, it displayed an error only to my friends saying "The game session has ended." It still connected me to the server.

We separately found the same servers on the list and played together that way, but is there a workaround for this issue?
