1. get EAC Error kicked (Moderator Kick may work the same, unsure because ppl don't kick me)
  2. attempt to rejoin that instance
  3. see 0,0,0 for a few frames and get booted to random Public instance
It took me over an hour and a support ticket to realize why this was happening.
There was no error explaining that EAC error kicks tempban for an hour from that instance, so I had to take to the VRC Discord to find out what the hell was going on.
This ABSOLUTELY NEEDS an error message in the client. The fact that it doesn't is crazy.
I don't even know why I started getting EAC errors recently, but what bothers me more is how long it took me to figure out why I could not rejoin, and needed to waste the Discord's time to do so.
