Possibly replicated bug with NPCs dropping their weapons

[Salty-Panda]

Describe the bug

As described in #45865, NPC for no visible reason drops their weapon.
It might happen both with player-owned NPCs and those belonging to other factions.
Until now, despite a few tries, I was unable to reproduce it.

Steps To Reproduce

I happened to test some unrelated changes while breakpoint related to this issue triggered.

I think the problem is as such:
NPC when not doing anything might attempt to try to find and equip a better weapon.
Code visits cached inventory, function returns some better weapon.
NPC puts off their current weapon (probably dropping it) and tries to wield a better one
NPC is not allowed to pick up loot, function stops.

Tomorrow, I will probably try to change a chance to trigger this check to once per minute and try to inspect reproducing this bug further.

Expected behavior

Check whether NPC can actually pick up a better item before dropping the current one
