Earlier, me and my friends decided to go to The End on our server and kill the ender dragon. When we went in the portal everything looked fine at first, since BetterEnd mod's blocks and structures generated right. But after we killed the ender dragon and went to the end islands, I realized that the BetterEnd mod biomes didn't generate at all, but the BYG end biomes did. It was confirmed when I used the Nature's Compass and even teleported thousands of blocks all around the end, not even /locatebiome worked. Yet the ores and mini-structures from BetterEnd mod still generated.
I tried deleting the DIM1 file multiple times and The End still generated the same way 3 times. Is there anyway I can change the way The End is generated through a different way and get the BetterEnd biomes to generate? I'd rather not reset the world as me and my friends had made a ton of progress.
The Minecraft version is 1.16.6, BetterEnd version is 2.5, and BYG version is 1.3.5.
Edit: Recently just created a single player world, and everything generated perfectly fine with the same mods and versions I'm using on the server. I also tried manually adding The End files from the single player world to the server, and it only added a single biome, and the rest was the same.
