So i am new to using mods, and i am using a modpack i made. So here i was playing like usual, then i decided to get more mods. So i went out, got my mods, then i launched minecraft, then i spawned a bird, killed it, then it said Loading world for a split second, and then a fatal error has occurred. Please help me, i have a survival world and i made alot of progress on it!
