For some reason I have one pawn that keeps hoarding every weapon she picks up. If she hauls a weapon, she does not put it where it goes and instead just holds onto it. If I don't catch it she will somehow be carrying 200kg worth of guns and my entire game will lag to 2 FPS when i select her. How do I stop her from doing this?

I think it might be caused by Research Reinvented, because she picks up guns to research them, but I have another pawn that also is a researcher and she doesn't hoard the guns she researches.
