Hi andrew, thanks for the bug-report. I'm unable to replicate that issue on my end. I'm able to create a new game, and the map generates successfully - and I'm then also able to form a caravan, settle a different tile, and successfully generate a map for that tile.

Perhaps there is a conflict between this mod and one/some of the other mods you have active? Could you post your mod-list here, please?
Assuming you're using Windows, your saved mod-lists can be found at the path: "%USERPROFILE%\AppData\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios\ModLists".

I think is gone after I disabled and enabled the mod again.might because I drag mod files in mods folder and replace old one instead of using workshop . Anyway, thanks for maintenance and updates this mod.
