Players controlling many tribes simultaneously

Yesterday I found one player with 10-20 tribes simultaneously, all named the same, all in one small castle - you could not kill them, there were too many archers. Even though only one tribe was updated, the others basic, this was too much already.

Today I want to play again and after <1 minute in game, I get overrun by multiple tribes, all with the same name, running wild throughout the map, seemingly looking where new players spawn to kill them instantly.

Please review and fix, as this is making the game pointless and dull
