Okay so today there were 3 server restarts and on the last server restard something happened with my tribe.. When i came back online i checked the history logs and it appeared something like "[auto]".. I was the tribe leader and now another person got the leadership.
Is it something related from the server restart which caused the problem or?

This also happened to The Furry Revolution.

I checked one of my alts and this didn't happened to my 4th tribe.. I guess it's not for every tribe.
