Re: Unplayable Granite Falls, Probably Due To A Mod.
@ChysaVR Have you removed the mod that was causing the issue? If not, that's the place to start.
If that doesn't help, try disabling Outdoor Retreat, still with the mod removed, and loading your save. Everything from the pack will be gone, but your save should be fine overall. Use "save as" to rename the save so your original isn't overwritten, then see whether your sims can visit the lot. quit, reenable Outdoor Retreat, and see whether you can visit the lots. Here's how to disable a pack from loading:
