Having the same issue.

Same

Having this issue too. The priorities keep reseting to whatever they were originally set at when the prisoner was captured.
Edit: I see where the "allowed work types" can be set in the mod settings, that fixed this issue.

I have it set to allow everything I want but it sill happens, idk still haven't found a fix for it

I was running into this issue too, but then I re-read the mod description, which says: "Prison area - prisoners in order to work need to reach target. You can check "Hold open" option on doors. Be aware, they will try to run if they see opportunity."

As soon as I made sure the prisoners were able to reach an area where they could do their assigned work type, the work priority stopped resetting. I would think this feature would be more explanatory if instead the work priority didn't reset but there was a popup saying something like "prisoners are assigned to <job type> but have no reachable work areas"

My pawns can reach their work area, nevertheless, the job priorities, with a few exceptions, keep resetting every load.

I'm having the same problem.
i.e. one of prisoner pawns were assigned to surgeries on capture. Now I cannot forbid him doing this work because it keeps resetting.
my entire base has held open doors but some assignments keep disappearing. So annoying

Anyone with this go into mod settings and enable all job types :)

Everytime I switch to my colony's main work tab it resets my prison work tab to prior category settings... for instance if I change my prisoners craft from a 2 to a 3, then switch to my colonists work tab and back to my prisoner work tab, the 3 will revert to 2.
