Taking a sim to a community lot, switches to buy mode when arriving?

[Hammie]

I took my Sim to a pet store to buy a collar for a dog, and when he arrives (going by car, walking or otherwise) the lot is in buy mode. I'm confused on why it's doing this. I'm very grateful for any help.

Couple of questions first to get more info, Does your sim not arrive at all then or they arrive , can be controlled etc , but buy mode remains on? Is it just buy mode or buy/build mode? Have you tried going to other comm. lots , if so , what happens? Same thing or normal behavior? The more info you can give , the easier it makes it to eliminate some things and try to start finding a solution. What you might think is overkill with the info , won't hurt and might help.
