1.12.2 Resturbed Mod Spawner Only Spawning One Mod of Spawn Egg Type Then Reverting To Original Mob

[DizzyDJW]

So basically, once you use a spawn egg on a vanilla mob spawner to change it's type, after you use a drop of evil to get a resturbed mod spawner, it lists the mobs inside from the original to any spawn eggs used on it. It only spawns one of the ones in the list, then reverts to whatever mob was there previous to using a spawn egg on it.
