I and more people get this crash:

When an EnderZoo Fallen knight spawns, it should have no random enchants at all on its armour and weapon, because they turned all the weights to 0. The EnderZoo people say that the Forbidden Magic Wrath Enchant breaks this somehow. Could you take a look at how to fix this?

It is not that urgent for be, because it does not corrupt the world or happen very frequently, but I am running a multiplayer server and it is kind of a hassle restarting the server every time this happens.

The EnderIO version of this issue.

So... was this fixed in the 0.561 update? Or do I have to wait a little more before I can lift the "curse of peacefulness" that I cast upon my server?
