Items Removed Warning?

I've been getting this message lately after installing growing together. I checked my sims household inventory and they have a bunch of furniture and items that I never had in their current home before. Every time I load up the family, I'm told something has been removed, like the message you stated but it's nothing on the actual lot removed. I'm not sure if it's deleting stuff from the household inventory though. I checked to see if any of my sims are kleptomaniac and they aren't. I noticed a debug gift box that's in the regular buy category too. I don't think that's suppose to be there.
