My prisoners are stuck in their cell block/individual cells. One left his cell to go to the shower but that is connected to the cell block. None of them will leave to go eat, work, etc. They are not blocked by anything. I have not hindered them in any way to entering the other rooms. I have tried having a guard escort them back to the cell they are already in but that does nothing. I have tried removing walls. I am not sure what else to try.
