Appliances break very easily

Not sure if this is a bug but I have recently purchased the Businesses & hobbies pack and since adding it to my game, the toilets always seem to break.

While my family business was open for  8 hours, my sim had to repair the toilet 6 times. The toilet had not been pranked and it just breaks after being used once. I tried buying a new toilet and upgrading it but the issue is still there.

It's just getting to the point it's frustrating because I know I'll have to repair the toilet after using it (but repair skills are so high for all my sims)

I have no mods, play on the PC.
