Whenever I drop something inside the house in Megaton, outside of a container, after it stops moving it will turn invisible. I can still interact with it, pick it up and all that but it's invisible. Not invisible in the stealth-boy sense, but completely invisible.

I recall Morrowind and Oblivion had these containers called Overflow Loot Bags which would appear if too many items were dropped in a cell outside of a container and all "overflow items" would be inside it however in Oblivion I know this is hardly obtainable without cheating methods. When I leave and come back in F3 there's no container, but the invisible items are still there. Is this how Bethesda implemented OLB in this game or is this a bug?

For the record, it doesn't matter what it is, where I drop it in the house, how many I drop at a time, and if I drop an item outside the house it won't go invisible.
