Issue description

Whenever I try to run the mod to test it in the Java client, the mod errors, saying "java.lang.NoSuchMethodError: mod.mcreator.mcreator_alemoniumOre.(Lmod/mcreator/crmod_for_1121;)".

The mod builds fine, but can't run. Any ideas on what's going on or how to fix it?

Issue comments

Do you get this error in test Minecraft or in the standalone client? Please paste the whole log too.

Based on this: crmod_for_1121 you are running your mod on 1.12.1, where 1.8.3 is made for 1.12.2 so this would be definitely a reason for your mod not working.
