I am using Biomes o Plenty, Immersive Engineering, and Immersive railroading, Engineering and Biomes work fine together but when I add Immersive Railroading (And TrackAPI and Universal Modcore) it just says "Safe Mode" (Vanilla Minecraft) and "Go back to main menu to try to fix problem manually" I try removing Immersive Railroading, and once again, works fine, I try removing Biomes O Plenty and adding Immersive Railroading back in, but nope! Same error! I have no idea what to do, any ideas?
