Hey!
On disabling an ore type:
Nope, setting Stone to OFF won't make it run vanilla. it'll just stop the plugin from spawning stone entirely. The thing is, if you have Disable Native Spawning set to true (which is the default), the plugin blocks ALL native/vanilla ore spawning via a Harmony patch. That patch doesn't care about individual ore toggles, it kills all native ore populations across the board.
So if you disable Stone but keep native spawning blocked, you'll end up with zero stone nodes on the map. Not vanilla, just... gone lol.
If you want a specific ore to be fully vanilla, the cleanest option right now is to:
Set Disable Native Spawning to OFF in the Advanced tab
Then disable the ore types you don't want the plugin to manage
The catch is that native spawning comes back for all ore types at that point, so enabled ores will get both plugin + vanilla spawns (more nodes overall).
