Ore Respawner

Ever come back to your old cave network and find it completely picked clean? Every ore vein gone, every gem cluster mined to nothing, just empty tunnels you have to dig past to find anything worth grabbing? On a server that runs for weeks, the whole map ends up like that eventually.

Ore Respawner fixes it. Ore and gems slowly grow back in caves, so the places you've already explored stay worth visiting instead of turning into dead space.

Perfect for multiplayer servers to ensure new adventures have access to resources without having to travel to a completely empty region.

What it actually does:

Ore grows back inside the rock. The mod takes rock walls that are still standing and turns some of them into the ore that belongs to that rock type. Forest rock gives you copper, iron and gold. Deep rock gives the deeper ores. Snow, swamp and desert rock each give their own variants, and modded ores are picked up automatically. Ore only ever shows up buried in solid rock the way it does when the world first generates, never floating in the middle of a tunnel you already cleared.

Gems grow back too. When you mine a crystal cluster it leaves that distinctive gem gravel on the floor. The mod reads that gravel and regrows clusters on it, so a gem patch keeps its spot and comes back even if you stripped it bare. Mostly small clusters, with the occasional bigger one.

It all happens gradually near players, so caves recover at a steady trickle rather than refilling the second you turn your back. The pacing is tuned to feel natural out of the box, so there's nothing to set up. Install it and it works.

Things worth knowing:

All the work happens on the server. It adds no new items, no new blocks, and nothing client-side, so it won't clash with your other mods or your interface.

It is still a normal mod, not a client-optional one. Everyone playing on the server needs it installed, the same as any other mod, or the server will turn them away for a mod mismatch.

It stores nothing in your save file. It only ever changes tiles that are already in the world, and those changes sync to every player the normal way, so no desync or rollback weirdness.
