Pizza Bug

I have my sim order a pizza. The Pizza sim arrives and delivers the pizza, not problem...my sim sets the pizza on the counter. Then instead of taking a slice, I had my sim "put away" said pizza...but she walks right by the fridge, goes upstairs into the library and puts the pizza in the bookcase...when i open the bookcase inventory there is no Pizza, nor is it in the fridge's inventory. So, this cheese pizza has somehow fallen into the void. No idea how it happened, it's never happened before. Doesn't seem to break the game or cause any other issues. Just a missing Pizza. but just thought I would report it.
