It's a game issue -- there were discussions here a long time ago (at least a year or more) about custom lots that came with odd objects having problems, and putting weird files in your downloads folder (usually 0 bytes). Back then it was things like a single toy from a toy box, but no toy box on the lot for it to be associated with.
You can try deleting the two stray items from the lot, leaving the game, and checking to see if you have any 0 byte files in your Downloads folder. If yes, just delete them, and that may fix the problem. Or, a simpler approach is to use the Clean Installer to scan your Downloads for 'empty package files' (they show up highlighted in light red/pink), and deleting them that way.

I'll try that, thanks. Though, I did use the clean installer to install the lot, I always do, and the only file was the lot itself.
