I made some edits to Calixto's house in my mod and I decided I wanted to do my mod differently, and I'd like to put Calixto's place back to how it was. How do I go about removing the modified cell from my mod so only the original shows up in game? If I load just the main file the cell is fine, but with my mod loaded I can only see it with my changes. I just want it back to how it was :C

You can use the File > Data > Deatails window to "Ignore" (Delete key) the cell's children (placed stuff), then save. If the CELL form has no children and is identical to the master iteration, it should also be removed automatically.

I think that did the trick. Thank you!
