Probecore SAS Stops Working after Scientist EVA

[Tynrael]

Bob is my main guy, I truck him all over for the extra science boost and leave him a dedicated probecore to manage the difficult piloting. I would say a large percentage of the time I EVA him to pick up surface samples I will get back to my rocket and start my ascension back to space only to realize that I flail all over with no stability, even though SAS is on and lights up. I have power, I choose to control the ship from the probe core, and get no results. I have tried disabling/re-enabling SAS, changing control to something else and then back to the probecore, as well as saving and loading. The only guaranteed fix I have found for this is to go back to the Space Center and then back to the ship (which is not ideal if my ship is falling).

Has anyone else experienced something similar? I am not sure if it is mod related, I have a list in my signature.
