Hello. This message just means that you have either deleted coal_ore.hjson, replaced the value name inside of it, or disabled vanilla support in the config file without removing coal ore from the block list. Can you confirm that none of these have happened? If so, please share your config file and I will try it.

the same happens to me, I haven't changed anything and it throws that error, both when downloading from the curse forge page and the launcher mod menu.
I would send you the config file you told to send, but I can't seem to find it. could you please tell me where in the .jar file it is?
I am playing on 1.16.3 if that helps.

Just discovered this mod and wanted to try it out on 1.16.3, but ran into the same issue. I tested it with no other mods on Forge 34.1.18, using the default config for OSV.

The good news is, I think I've found cause of the issue. It seems that osv-common.hjson is being read before the config/osv folder is generated (which has the default ore files, such as coal_ore.hjson). Removing all of the default entries in propertyGroups allows the game to load and the osv folder to generate. Then you can re-add those entries and it appears to be working (for instance, I have found andesite coal ore).

Anyway, it should hopefully be an easy fix, and this workaround does the trick for now. 🙂

Hello. Sorry this took me so long to get back to! I've been practicing web development lately for my new job and just really need to devote my attention to that for a while. I believe I have fixed this bug now. Please unzip and try out the new version below, if you have the chance.

Thanks again!
Ore Stone Variants-5.7-1.16.3.zip

No worries. I downloaded and tested the new version and it seems to be working fine - no errors, and I found some diorite coal ore right away.

Thanks for the quick update. Now I just gotta wrap my head around these configs... 😅

Good luck on the new gig!
