Purpose of change

Fix tidy-up activity not working for NPCs

Describe the solution

This was fixed in one of my NPC activity PRs in feature freeze, but I may as well split the fix out because its stopping me testing other stuff.
In the activity loop, tidying up items dosnt work because of a misplaced edit to the if/else structure branch, overwriting the list of locations.

Describe alternatives you've considered

N/A

Testing

Before : NPC did work, left things lying everywhere.
after : NPC tidies up activity items to an unsorted spot, as intended.

Additional context

Ah, so there was a bug! I've been wracking my brains for days trying to figure out how I'm messing up loot zones and getting incredibly frustrated. Thanks so much for this!
