AI players appear when human player restarts mission

[Rich_R 1087]

In the last few weeks we've had the following issue on our MP server. Bear in mind, we have no AI in our squad.

 

Everyone spawns in at the beginning of the mission. For whatever reason, player Joe restarts the mission. An AI takes over Joe's ingame character. When the real Joe comes back in game, we have one AI Joe and one Human Joe. We cannot delete the AI Joe with vanilla zeus.

 

Tried googling this and couldn't find anything about it. Any help would be appreciated.
