The new, added school buildings were full of hunting jackets and pants. I noticed a trend with the hunting pants especially, when you go and swap pants that are on the ground, your previously equipped ones tend to disappear with anything inside them at the time.

I know item disappearing has been an issue / is known, but usually the 'disappeared' items pop up at doorways, rooms up or below etc., but in the school building, I haven't been able to locate the many pants I lost while trying this out.
