I built a small Protected Custody wing for snitches, ex-law, and other at-risk prisoners. The wing is enclosed and includes both a yard and a canteen, and all the cells have all the amenities a prisoner might want.
Unfortunately, the protected custody inmates occasionally end up outside their wing. I think they're trying to eat at the regular canteen or exercise in the regular yard. This is almost always fatal.
The entire wing is designated protected custody. Most of the rest of the prison is Shared to accommodate a 50:50 mix of max and medium security. Designating it to medium and max (unless there's a way to make it both) would require redesigning the whole prison and I'd rather not have to do that.
Their regime does not include work- it is sleep, lockup, eat and yard. I used to include free time before other prisoners are awake.
How do I keep my protected prisoners in their own wing without setting them all to permanent lockdown? Ideally giving them free time (within their wing).
