Items in Sims' inventories not draggable

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.71.86.1020
What expansions, game packs, and stuff packs do you have installed? All of them, Kits included
Steps: How can we find the bug ourselves? Try to move items from inventory.
What happens when the bug occurs? I have multiple sims who have moved from one household into another or into one of their own. They are spellcasters. Most have potions, but they also have a lot of harvestables in their inventories. Since moving, they cannot drag these items out of their inventories into the world. They can only choose "Place in World" in the case of things like flowers or fruits, or they can eat them. They also cannot sell them. With the potions, it's the same. They can drink them or place them in world. They cannot drag them out. It's pretty frustrating. One sim even has a painting (of his own) that has NO options. He can't sell it, drag it out, put it on Plopsy or anything, It's just stuck there. It's not happening with EVERY item... but it IS happening with most items, and it's seems to be only happening with items that they created/harvested before they switched households or moved out on their own.
What do you expect to see? To be able to drag items out of my sims' inventories and/or to be able to sell them.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? No

I removed my mods and CC. I tried repairing the game. I cleared my game cache. I also switched households. I even moved the household it's been a particular problem in to a new lot. None of these things fixed it. 

I *think* this began only after I bought and installed the new Kits, but I can't say that definitively. It could be a coincidence, timing wise.
