down the prisoner and remove the prisoner perms on the bed, then your prisoners should be transported to your new prison cell. releasing a prisoner does not work unless they are on the ground floor

Reup because I can't get any prisoners down to floor -1.
Only prison beds available are underground, indoors, 21°C, but when I try to capture a downed prisoner (new or old) "there is no reachable prisoner bed in safe temperature".

The prisoners also never go down by themselves (prison labor mod).

Can't we have just a hole in the ground where you can toss them (maybe with or without falling damage) to get them at least downwards?

EDIT 1:
AND literally 5 seconds after posting another colonist could take the prisoner down, what my first pawn could not.
Interestingly, the first pawn was Vanilla human (but with Rimworld of Magic class), the second one was a modded race (Dragonian).

But I stay with my wish for a hole to drop anything (prisoners, items, ressources...) from one floor to another...

EDIT 2:
Still can't bring down all of my prisoners. Can't find the reasoning behind it, regardless the race or traits or whatever of the prisoner or the colonist...

And now most but not all of my prisoners have a bed with their name on it on floor -1, but to work (again: prison labor mod) they come to floor 0. Then night falls, they don't go back to their beds, but instead sleep all on a single tile in my bathroom...
That's kinda wholesome I guess but not what I intended.
