I think Enderman Evolution is currently bugged - or at least, it makes the pack incredibly annoying.
In the config file you have it set as:
which should stop the evolved endermen from spawning wherever they want. Despite this, they still spawn all over my fully lit island, and are more than happy to steal blocks. I'd rather not have to spend my entire game staring at the ground to avoid having to fight endermen.
There's an issue thread on the project ozone lite page stating that this config setting flat out doesn't work. The issue was closed by the pack developer because "More enderpearls". See here: https://minecraft.curseforge.com/projects/project-ozone-lite/issues/97
It's possible that some other mod that both this pack and that one share is conflicting with the setting.
