Element Display Case

Idk if anyone else is having problems with it; I am having the trash, sink, and pregnancy issues though. But it won't let me drag the elements to the display case. they just keep popping back into my inventory or onto the floor. I'm trying to collect them with a sim made a few days ago for me to turn into a fairy once i get the new pack and I thought the elements would be fun for her to collect. I've gotten them before, and they worked fine then. I had mods then and I have them now, the only thing different is the other bugs. really hope this gets fixed soon. had to install a pregnancy test mod so I could take them, but I can't for anything else. Hoping they're fixed by next week when I get the new pack!
