Since we are only generating 100 drop mappings per mob per enchant level, the chances of getting an enchanted item are pretty low. This also means that there may only be one in the 100, so you always get the same enchants.

So when the enchanted item is in the drops for the factory to produce, clear and randomize the enchantments.

The chance to get an enchantment in the 100 test spawns is TINY and you may not end up with one. Need to rethink how to handle this.

Still doesn't fix it. You can get the situation where there are NO enchanted drops in the sample size, so you will NEVER get an enchantment.
