The WARDOGS Discord warned that some players are getting banned simply for trying to join a server. Developers already know the cause and are working on a fix.
Who is affected
— Players whose accounts are somehow linked to FirstLook.
— Those who took part in past internal tests — leftover old access permissions are now conflicting.
What the developers say
— The cause of the bug has already been identified.
— A fix is being prepared and will be rolled out as soon as possible.
One week into early access, and the first systemic bug hits not gameplay, but the very ability to get into the game. It's unpleasant when you get banned for nothing at all.
