Yeah I hear ya. I started a new world and was holding of on a lot of exploring, waiting for the caves update.

But my main, most used world i have been all over. thats the one I tried the reset of the area mod. worked easy, and you uninstall it after word. can select specific areas, so not the whole world. and it "auto" detects your bases. I had no troubles with it. and also backed up the save, before I used the mod on it.
