Same. I created a tribe 2 days ago and have the ability to create 4 more, but nothing happens when I click the button. No feedback, error message or anything.
Maybe it's something happening to everyone? Do you know who we can PM about this?
I tried again last night and it was working again. Created 2 more tribes.
Praise the gods! It works! Snapzu, say hello to /t/streetart and /t/gamersdilemma!
