More Context:
This happens two times on first "login." This might be due to a server clock reset? I am not sure
Once the player is broken and does not have group chat, the player remains broken for further lobbies the player joins.
If the player creates a lobby and another player joins, the player will have the "group" chat but no one receives the messages the player posts in "group chat"
If the player relogg, the issue is fixed.
I don't think this is random at all. We are missing one step. Perhaps, one of the client devs can take a look at this in-real time if they are available and if I am able to reproduce?
