Magic Beans
I have seen this in my game from time to time with various collectibles, not just the beans. Basically, since the items aren't being recognized as owned by your sim, they won't get counted for the collections. But I have found a work around of sorts. If the items are in your sim's inventory, you can gift them to another sim in the household and then they seem to get counted as owned by that sim and for the household and will get counted in the collection. So you might want to give that a try. But it does require more than one sim in the household. So if you're playing a one sim household, you might have to add a sim temporarily to get it to work. Sometimes, even though your sim can't pick the item up since it's not owned, you can drag it into the sim's inventory. If you can't then, you should be able to sell it in build mode. I've found that this usually happens when you move a sim via the move out and split household options on the phone or computer. It usually doesn't happen when you split the household via Manage Households.
Hope this helps.
