Hi! Faced with a huge problem. Literally today I downloaded the mod and everything necessary for it, but after getting to The End with the help of the teleport command, I literally have only a HUD and one type of mobs that spawns itself. There are no new blocks, no structures, no new biome - nothing at all. Although the creative mode menu has absolutely everything. What did I do wrong?

Could you by chance post your mod list, launcher, and forge version?
