Unable to arrest the temporary colonists from creepjoiner event if they're holding a weapon

[ThisIsSP4RTAN]

Describe the bug:
If you attempt to arrest a temporary colonist from the creepjoiner event that's also holding a weapon, your pawn will fail to arrest them. You are also unable to force the creepjoiner to drop the weapon directly on the ground. You have to make them unload the weapon into storage. If they decide to leave and you no longer have control over them there's nothing you can do.

Expected behavior:
Colonist should arrest creepjoiner and the arrested pawn should drop their weapon

Steps to reproduce:

1. trigger a creepjoiner event
2. allow them to join and give them a weapon
3. attempt to arrest them

Excellent bug report and save file, thanks!

Looks like the fix implemented for #84 is throwing a NullRef - I'll have to poke at this a bit further.

Turns out I should be using pawn.MapHeld instead of pawn.Map.

Could you please try the following dev build?

I'm getting additional reports that the fix from #84 is causing more problems that it solves, so I'll roll back those changes and do an emergency release, then figure out an alternative solution to #84.
