You're very welcome, glad I could help! Ohh, so it did turn out to be a mod then. Well, I'm glad you got that sorted out and everything is working now as it should. Those produce stalls are great for non-gardening Sims, I have a couple. Most of my Sims usually have a garden or greenhouse though. But it's nice to know that's an option for those who don't have one.
That's one reason why I don't use mods/cc so far in TS4, they seem to interfere a lot with the game, I see other Simmers with problems on here all the time. I'm not opposed to them though, I had TONS in TS2 and loved every one. I'll probably try a few at some point, but for now I'm having a lot of fun with my vanilla game.
Happy Simming! <3
