In my save, it seems that the calcite and tungsten veins on Vulcanus still deplete. I did not turn on Infinite tungsten in the settings before, but when I noticed that the veins were about to deplete, I turned on the settings, but it still didn't work, the veins still depleted afterwards.

The mod is set up in a way where the number will still go down when the mod is active, and it will only replenish the ore when the very last ore in a given patch is mined. On your save, did the patch ever fully run out? If it ran out completely without refilling while the mod was active I will look into it further.

Hello, yes. When I had the "Infinite Tungsten" mod enabled, the tungsten still got depleted. I even converted my save file and tested with the map editor while keeping the "Infinite Tungsten" mod active. Using a large mining rig to mine tungsten on Vulcanus, I focused on an ore patch covering only 1 tile (with about 200 units). After some time, the ore in that tile was fully depleted as normal.

I searched the mod portal and couldn't find the "Infinite Tungsten" mod. If you are just using this mod, could you check to see if the refill tungsten setting is still on in the mod settings (though it should be on by default). I booted up a brand new save and tested if tungsten refilled right out of the box on the latest version and it did, so I am unsure what the issue could be here. If you have more details about the exact mod list and version being used I can take a closer look at what exactly is causing the issue
