I just recently started using your mod and I added it to a custom modpack me and my friends use to play. While making the armor, I found that it did not work as expected and the armor would display as just normal armor while on the player, but on an armor stand, it displays correctly. I did some testing and found out that the mod Mo' Bends seems to cause this issue.

Just found out that Mo' Bends has an experimental version that fixes it. Nevermind.
