Sims won't leave small business lot when business is closed for the day.

Immediately after purchasing and installing Business & Hobbies expansion and registering business, I opened it and had a good influx of customers/sims. After deciding business day was over, I closed the business, but the sims present on the lot did not leave, and continued to come and go as though the business was open. I have even tried bulldozing the lot and replacing it, but all the sims just walked back onto the lot and went back to their previous state. Additionally, when locking doors (lock for everyone except household memebers), sims can still enter and exit as they please with no options available to ask them to leave or preven other sims from entering or exiting the lot. 

I did have some mods installed, but when mods were disabled in settings, the issue still persists with no avalable options to allow the player or household sims to get customers to leave.
