When pawns are downed they drop whatever item is in their inventory, typically a meal, which is un-forbidden, meaning your colonists rush out to collect it. Apparently foreigners bring amazing Happy Meals or whatever and they smell irresistibly good? ??? Dropped items should really be marked as forbidden, thanks.
as stated by kaballah, anything in their inventory is un-forbidden when dropped. the sliver, the medicine, the meals.
nothing worse than a doctor running clear across the map for that one medicine, when you have 100 herbal meds right beside the hospital bed.
Fixed now, thanks!
