Storage capacity dropped at end of mayors pass

I bought some SimCash with real money, then used that to buy 5 more storage spaces, taking me up to 115. I still had that storage this morning, but roughly 5 hours later it’s gone and I’m back down to 110. My SimCash and simoleans are as they were after purchasing the extra storage, so I don’t think the game’s reverted to an earlier save. How do I get my purchase back? 

UPDATE: I reported the problem and was sent a copy and paste email from someone who clearly hadn’t understood the problem. For the next customer service person that reads this: IT WAS NOT TEMPORARY STORAGE. I PAID FOR IT SEPARATELY FROM THE MAYOR SEASON PASS.
