The newest versions of Forge, specifically those after 14.21.0.2348, are breaking many mods. Amongst the broken mods is Simple Ore Generation.

I'm going to assume, that it just means Forge changed something, and that rebuilding the mod on an updated version should fix the issue. I'll do that right now, and upload the jar to the Github to test. If it solves your problem, I'll upload the fix to curseforge. :)

From another mod's author's comments, it seems that Forge has made a breaking change to one of their registry systems. Apparently, those paying attention to such things were aware of it in advance, although perhaps not the timing...

Anyway, I'll not be able to test this until Sunday afternoon or Evening.

[Rohzek]

I see. The only registry change I was aware of is the differences in crafting recipes. I'll guess I'll be figuring it out, though.

It's quite alright though, no rush. As long as Forge doesn't have a stable release, problems are expected to happen.

Here's a quick link to it. :)

I gave it a try, still failing. But from what I'm experiencing and have seen with other mods, other people are trying to keep their mods current with Forge but also failing. Right now, it's hard to know which mods work with which version of Forge.

Should hopefully be fixed in the latest versions, now that Forge has a stable, recommended release.

[Zarepheth]

It's now working, but I had to follow the advice on about deleting the OreGen.json file to clear the startup errors. And doing a comparison between the old and new OreGen.json, it looks like you're now handling more ores, and improving the mining level.

Glad everything's working now. :)
