Does uptown ever get food carts or the grocery stand?

No problem! I do feel like something may have changed in a patch with the vendors though. I have been playing with SE, and noticed that the stall by the ski lift only gets a vendor during the snow festival. The other stalls in that world work fine, and I don’t see a “stuck” vendor Sim anywhere. I’m intrigued and want to investigate.. however it’s 4am for me, so I’m off to catch a few hours of sleep. I’ll try to test a few out if I get a chance tomorrow.
