My restaurant won't show me information for my business

I've never used this site so bare with me please ;-;

So, I own the dine out pack and a little while ago my sim bought a plot of land and built a restaurant. Up until now, I've had no issues with viewing my business's information, regardless of whether or not I've been on the lot or which Sim I'm currently playing as in the household (I have 5 sims in my household), I even opened the restaurant whilst my sims were at home and everything went fine. However, I decided to travel to the lot to open the restaurant so that I could oversee my business for the first time in a while. I opened the business panel and used the 'travel' option on the restaurant page just fine, but as soon as I did that, all my business information disappeared when I loaded onto the lot. I tried repairing my game twice and nothing happened. I even sold the business (because it still says that I own the business despite the business panel saying I don't own anything) and tried buying it back but nothing happened, I never even got my money back when I sold it despite the game telling me that the funds would be transferred back to my household. I have no idea what's happening. I own a bunch of add-ons for the sims (including the new For Rent pack if this is relevant in anyway) and I don't use any mods or cc because they're too much effort to get installed. Any ideas on what's up or what I should do??
