Happened again... :/  My tribe was at the first place, but then got the message "SERVER IS DEAD" all of the sudden. 

I've opened a new tab, entered the game, and the server was still active, all the same players/tribe names were there, even my tribe was there, but someone else was controlling it... 

It just happened again... This time I DIDN'T refesh after getting the message that the Server is dead, so I was never disconnected from my side. I left the tab opened with the message, and opened the game in another browser, the server was running fine, all the players were there, my tribe was there (again I was at the first spot), tribe was alive, and SOMEBODY was CONTROLLING my tribe!!! :D WTH?!
