I have the categories of aether mod in creative mod, got the config file too but when i try to open the portal it's not working.
Downloaded the mod from curseforge.
I was about to go the end suddenly realized that i need one more eye of ender, so i started looking for endermans. But i couldnt find any, and there was no hostile mobs around me, i was like "what the, something is wrong"... Tried to sleep and wait for another night, but nothing changed. Only friendly mobs are spawning not hostile ones.
I did tried gamerule domobspawn thing.
