Errors being thrown when using custom NBTs and Lore together

Issue

When using items that have custom NBT and lore the following error is thrown pretty much everytick the item is active: https://pastebin.com/ExBtUKyM

This also happens when using MMOitems that make use of the Crucible NBT tags.

If you remove either the NBT or the lore the item will work with no errors, but you can not have both on at the same time.
