Huge thanks to Kastle for helping me disect this behavior. - The Unbreakable NBT tag is not the only source for determining if an item should be treated as unbreakable. The damage NBT is also taken into account. - Custom item options must be processed in an ascending order. - Multiple conditions may be necessary for an item to be selected. - Conditions do not have to be exact. See the comments in CustomItemTranslator for an explanation. - Added a test so we don't break this behavior in the future.
