Awhile ago we disabled the ability to get custom enchants from the enchanting table. It is now time to remove it from the server entirely as it seems that it is interfering with vanilla enchanting in a negative way. I am hoping to wait until after we update to 1.12 to add in the replacement enchants so please, be patient.
If you have items with custom enchants (non-vanilla and not from the mythic drops as all those still work) then the custom enchantments will stop working, HOWEVER, do not get rid of those items! We will have a plan in place to allow for trading in those items for similar enchantments under the new system.
If you strongly oppose this removal of the enchantments for this (hopefully) short period of time, please let me know. I am always trying to keep your best interests in mind and I am always open to your opinions.
As always, if you have questions, comments, or concerns, please post below.
