Issue Description:

when i use any spawning type machine ive tried the powered spawner and draconic spawner to try to spawn wither skele but it says its denied by a mod anyone know whats doing this im on direwold20 pack

You have a mod installed that says "NOOOOOOOOOOOOOOOOOOOOO, I FORBID IT. IT AIN'T ALLOWED!! IT'S VERBOTEN!!!" when we try to spawn a mob.

Simple as that.

so theres no way to get rid of it? so just do a normal skele spawner on the nether and do it that way then?

Or find whatever mod is stopping spawns in that area
