Randomly kicked off of an Endgame Server.

"You were kicked off the game. (Player SubtlyAgressive: Wrong signature for file C:\Program Files (x86)\Steam\steamapps\common\Arma 3\kart\addons\anims_f_kart.pbo)"

I exited the game (but not the launcher) and started it up again, and was able to rejoin the game.
