I'm running a lot of other mods, but this worked very poorly. It did as described but it also deleted a load of my roads/paths, ore was removed and not regenerated, trees were regenerated in locations that ore used to be. Maybe this is because I'm running RSO? Image below will show the problems described.

Enemies also started attacking me after I clicked, but I had peaceful mode turned on beforehand.

I am also using RSO and have the same issue.

This mod has vanilla resource spawning only, the game makes new chunks without this mod.

RSO compatible
