In 1.10.2, when using the non-vanilla table, any XP the player gets after that point is not added resulting in them getting stuck at a specific level. It seems the only way to fix this is remove all levels from a player.

• Get some XP (make some coal and mine it)
• Use the eplus table to enchant or repair
• Try to get some more XP (make some coal and mine it)
• No more XP is added to the player
• Type /xp -nL (where n is current level plus one)
• Try to get some more XP (make some coal and mine it)
• XP is added as normal again

Is there a way to fix this problem w/o having to bug the admins of the server?

This bug should be fixed in the 1.12.2 version of the mod.

Necro fix! Thanks for the update.
