This mod occasionally throws a ConcurrentModificationException on Forge when installed with other mods that don't handle ItemProperties::register properly, as that method is not thread-safe. This isn't due to code in this mod itself, but rather the PalladiumCore library that it depends on.

To fix this bug, you'll need to update your dependency on PalladiumCore to 1.4.1.1.

Lucas has made me aware, I am just trying to find time to sort that out
