I have been trying to generate an ore for my mod and have created a new feature and registered it. However, whenever I join a world, it immediately crashes. I cannot find anything useful in the crash report and am stumped. Can you find where I made a mistake?

is the FMLCommonSetupEvent in FeaturesInit fired?

is your mod load because the mod id is invalid, you can't use upper case

please use next time spoilers to post large code parts

I checked my code and my mod id was lowercase. There must have been an error when I copy and pasted it. I fixed my issue. The setup was not being called for some reason so I tweaked my code a bit and it now works. Thanks you for your help.
