Small Businesses & Retail Ownership Disappearing

Dearest of Support Gods and Fellow Simmers,

I've noticed recently that my small businesses are bugged out. My owner shows "You don't own any small businesses/retail stores" even though I have purchased property for both of these. Other sims show that they're employed by my sim's "nonexistent" small business, and every time I try to close it from the kiosk on my property, the sim resets and nothing has changed. 

I really would like to get these back. I found an amazing retail store on the Sims Community Downloads and I've been dying to play in it. Please help!
