Hello, i cant Use Immersive Railroading on 1.12.2 because UniversalModCore doesn´t work and i played 5 minutes ago with the mod and now it says that:Error: net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from UniversalModCore (universalmodcore). Game Crashed Because i tried to put in Your Recourcepack for Immersive Railroading That i get more Trains but something doesn´t Work i think the Recource Pack needs to be fixed Because it looks like The Recource Pack is broken. Please fix it quick because i love this mod!!!

I Deleted the RecourcePack out of my Recource Packs Folder and now it Works.
