What happend:
Client Freeze (no overlay, no nothing) for at least 3 players on the servers including 2friends on TS and me.
Happend happend first seconds of the match. EU SW, 1:44CET, server name unknown.
What we noticed:
My friend was in one team, I was in the other. The 3rd was on defenders in his client, however, we other two saw him in a spectator slot in the lobby! He says, he changed team in the lobby, but never to spec!
When the match started, he was a actually a spectator and wondering why.
A few seconds in, the game froze for all of us and we had to shut it via taskmanager.
