I removed all mods and custom content, started a new save file, moved my household into copperdale, and visited the bubble tea store. When at the store, vendor does not spawn. When trying to interact...
Ideas
Bug Fix/Workaround. If any mod users are interested.. LittleMsSams' "Auto Employee" works to add a vendor. After adding the mod, just click the door and choose 'allow vendor'.. I have used it, and a bubbletea table vendor shows up. I added some other outside market stalls, and they also showed up to them. 👍
