Inventory from plopped house showed up in neighboring house instead
Because there have been a lot of bug fixes lately and not all of them work retroactively, I have been playing in a new save. I played it for a couple of weeks and definitely noticed some improvements so I think that was a wise choice. I wanted to go in and add all the lots I have built so I can play them again (in this case, I dropped lots for all of the Parched Prospect section of Oasis Springs).
As I was going through the houses to make sure everything was OK, I found one of them was a totally empty shell. I thought I must have accidentally plopped it unfurnished so I replopped it and moved on. I play the Roomies and moved them into their new house and started playing. The lag was terrible and I never had issues with the lot before so I wasn't sure what was going on. Then I discovered that all of the missing objects from the other house were in this house's inventory! I deleted everything in the inventory and yes the lag from having an entire house in inventory was gone. However, when I had a Sim recycle from inventory on the recycler, around a dozen more items from that other house were available to recycle. None of those objects showed up in the house inventory or any of the personal inventories of the sims in the house, only the recycler menu.
How is it even possible for this to happen? Is this what happens in a corrupt save? Should I start a new one?
