Move characters and buildings to other worlds

I was wondering how to move a character and a “map tile” (lets say for example a specific grocery store) to another save. I know of the transfer utility but I wonder if I could transfer the building as well. What files would be needed to be moved.

You’d need to locate the map file for the map the character is on. The easiest way is to name some item (carve) some really recognizable string, then search for that string in all files in the save.
This one location will have bugged overmap tile, though. If you want to fix it, you’ll need to use debug mapgen function to override its overmap tile.

Thanks! Erronous map tiles should not be a problem if the rest of the map is fine.
