Yes I tested with the other game files, and it is just like you said, they get the profit and do not lose money.

The problem was in my custom neighborhood, because there she also restocks the rack. So actually the business runs at a loss even without employees. Perhaps it is my custom content after all. So I must test again without it, and see what happens.

Ripp first got the outfits from the rack. Lola immediately went over and restocked the rack, and -400 appeared over the rack. Then she went to the register where he was waiting. He handed over some money. The number 460 appeared over his head and 60 over her head.
I will try to upload a screenshot.

Hello, may I ask if anybody else might have noticed a similar problem like this, with businesses.

Lola has a boutique in Strangetown, and Ripp went there and bought 2 outfits à 230, and payed 460, but Lola only received 60. It happens all the time when I try to start a business  .

The first digit disappears every time, so when a bookstore sells a book which cost 32 simoleons the store owner only receives 2 simoleons. I wonder what can be the cause.
I took out the downloads folder, and put in on the desktop temporarily, but this did not make any difference.
