What the heck? When I opened the tribe interface thingy, that happened.
I swear I wasn't kicked out! Nobody who was online had the power to do so!

Reopen the tribe interface first, or reload the game. If it's not fixed, wait a hour/day to will fix. Or find a friend in your tribe to kick you and reinvite.

Its okay, I relogged and it stopped happening :3 Must of gotten fudged up...
