This is happening to me as well. The perk points reset to zero when you leave the lot (sometimes) or switch households (every time). You can't play rotational if you are going to own any business of any sort unless you don't mind losing all of your perk points. ☹️
This is the save that I noticed the issue in. There's a household in Brindleton Bay called Talla (there's actually 2 with that name there, you want the one that's a single dad with an alien son and 3 cats). They had all of their perk points reset just recently. I've now earned 550 points back on them but they are currently on vacation in Granite falls so they *should* lose them all when they get back home or back to the store.
