I'm having an issue with the storage container that comes with discovery university

Or, you could have her (or another sim) move to another lot with the chest, then move out and keeping furniture might unpack the chest and put all items in your sim's household inventory?

I never used the chest. If it could work as a "put furniture in your personal inventory" I'd gladly use it for sims moving out, but I don't want to risk losing stuff...
