I've noticed that the Only Autosaves option (at least when installed via BigWorldSetup) is causing areas to "un-explore" once you leave them. For instance, starting in the Candlekeep Inn, if you walk around downstairs to reveal it then go upstairs, coming back down all the 1st floor will be completely fogged over again. This is true for all interior areas around Candlekeep. I didn't test this any further in the game, as I immediately uninstalled the "No Autosaves" component and restarted, and the problem went away.  

I couldn't find this feature documented anywhere so I don't know if it's intended or otherwise.

This isn't really a bug (I don't think) but I couldn't find this documented anywhere, so I'll just mention it here:

In the Rough World submod, the "Only Autosaves" option causes visited areas to completely un-explore again after you leave them.
