When there's multiple things dropped, it can be very hard to "see" things you know are there, much less pick them up.
This is particularly difficult in the houses with fences. And there didn't seem to be enough horizontal space to drop things in many different places. I kinda had to put them into big piles.
I know this has been on the list before and that you'll figure a fix. I'm imagining a popup that tells you all the things in the pile, similar to when a butterfly passes in front of a tree and you're asked which thing you want to interact with.
