What you were expecting to happen, and what actually happened?
Received an invite from The Thunderbolts guild (Taisia)
Went to view said invite
Went to join said Guild
Error joining guild, saving user; 2 the service is currently unavailable, KrVC5cpnj42c
What are the steps to make it happen again?
Not sure what other than I was just kicked out of another guild earlier today
