I disabled every other mod and set the respawn rate to 5 but the ores do not respawn. Can you check if ther's any problem with the version?

False alarm. There was an option that disabled the refill by default so I unchecked it and it started working as intended. The lag shouldn't be a problem if i play in single player mode, yes?

Sorry for late reply, the lag is almost never a problem except on exceptionally large maps. It can mainly cause problems on multiplayer so yes, you should be fine. Even with it off ores should refill once they reach 0, but that does not work for oil.
