So... Im trying to launch my forge server (forge-1.11.2-13.20.1.2386) and it works fine really, but when I try to add these mods - Ad Inferos V1.2.6 and Think Big Core V1.6.1 (required for Ad Inferos to work), server keeps crashing! Plz help! ⬇️Here is my crash-report⬇️: Description: Exception in server tick loop net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from §e§k!!§6§k]]§c§kkk§4§lAd Inferos§c§kkk§6§k]]§e§k!!
