Hello, so what happened was I wanted to have custom and shiny starters in Pixelmon/Forge 1.12.2, and ever since I turned on that and a couple other things such as Ditto/Ditto legendaries, it won't load AT ALL. Here is the full error:
at net.minecraft.server.MinecraftServer.func_71217_p(MinecraftServer.java:668)
at net.minecraft.server.integrated.IntegratedServer.func_71217_p(IntegratedServer.java:185)
