I made my own modpack and was playing it to test how it runs. I noticed features weren't working and specific mods wont spawn
It's an alien vs predator modpack. I also have minecraft comes alive etc. When a villager dies you can summon the grim reaper and if you kill him you get the staff of life. But you have to use it on the item dropped from the dead villager. But I didnt get the item and the grim reaper wont spawn.
I had someone test it on my discord server (although he has the attention span the size of a peanut cause he immediately went to making a cannon and tries to launch himself as high as he could into the air...)
But he managed to get the grim reaper to spawn. I tried to find out if the predators and marines are spawning but like I said, he has a small attention span so he didnt even look. But his ran better than mine.
My only guess is the game has so much info from mods I used on different versions. Mods,modpacks etc so im guessing all the files in the minecraft folder are to blame. But it's a theory.
I dont know why it's doing this for me only.
