[Bug] java.lang.IllegalArgumentException when trying to render botania manasteel armor in cosmetic slots (sometimes)

[Colorblind22]

Is there an existing issue for this?

• I have searched the existing issues

Observed behaviour

Another player wearing manasteel armor in the cosmetic slot teleported to me and it caused a crash. This has been happening to me irregularly, sometimes it crashes the second they are within my render distance and other times we can be by eachother for hours with no issue. It has happened to other people on my server using the exact same versions of forge and all the mods.

This might be an issue with Botania or with Cosmetic Armor Reworked, or both. I have no clue. In any case the stacktrace points back to Wizardry.

Expected behaviour

For the armor to render correctly and for the game to not crash

Steps to reproduce

1. Log on to server
2. Have player wearing manasteel armor (from botania) in the cosmetic slots added by the Cosmetic Armor Reworked mod ver. v5a
3. Game occasionally crashes
