Summary:
While playing as Sturgian Vassal and sieging Flintolg Castle, I was attacked by Crotor and his party. I convinced him to join the sturgians (a 2nd time). BUT as I was sieging the castle and talking to him, once he joined my side, I was stuck in an endless loop of talking to him.
To end the loop, I had to use the chat option : "Join my army" wich required 20influence points ( which I did not have). He is now considered in my army and on his way.
After that I stayed bugged as the siege army camp.
