Bandaged Poissoner bug

My Bandaged Poissoner has not created a feast for the Fathomking, and therefore has not been upgraded to Bandaged Chef-Paramount, but I am at the Fathomking’s Hold with wine and am unable to proceed. Looking at my Learning About quality reveals that my Bandaged Poissoner thinks he has crafted the feast, but clearly he has not, because if he had, he would be a Bandaged Chef-Paramount. I feel terrible that this poor soul may be forever unable to achieve his life’s ambition, after having toiled so diligently at his art and come so very close he can taste it (and has). Can anyone help him?

Perhaps you should try support? I also got a series of bugs recently, previously unknown ones.
