Ive seen that it is difficult if not impossible to change spawning perameters for mobs. Im working on a skyblock server with ultimate stacker and silk spawners. When using an iron golem spawner the spawner as to be within two blocks from a floor vertically or it wont spawn anything. Is this a plugin problem making spawns different? I've never seen this problem before so not sure what to do. The only thing I can think is changing the spawn needs to be more vertically but not even sure how to go about this.
