[Bug]: Released prisoners equip weapons from player's storage

[clif08]

Rimworld version:
Combat Extended version: 16.7.0.0
Combat Extended source (Steam, GitHub, etc.): Steam
Your operating system: Win 10
Your mod list: Harmony, Core + DLCs, Combat Extended

Description
Whenever I release a prisoner, he or she walks a few cells towards the edge of the map, then turns around and goes to equip one of the weapons in my storage, typically the most powerful/expensive one.

Expected behavior
Normally released prisoner should exit the map straight away.

To reproduce
Release a prisoner not too close to the edge of the map while having weapons in storage.

This bug exists for a long time now. I was curious if it just happens to me because of some MOD. I'm tired of walling up my storage while releasing prisoners.
Maybe routine for reequipping weapon kicks in after release and should be fixed to exclude player owned weapons, or be disabled in the first place.
Edit: Shouldn't prisoners be unable to pass trough player owned doors?
