Hello again, I found a crash on a server with Upgradable Crystal Tools when holding a crystal trident in the main hand.

This caused me to be unable to join the server and would crash me to desktop.

Thankfully, our server has a backup mod and we restored it before I made the trident.

If there's any way you could repair this, I would be glad to continue testing. Thank you!

This is a weird one. It doesn't happen when you first load a singleplayer world and then join a server. I guess that is how I did all of my testing so I didn't run into this. Working on a fix now.

Should be fixed in 1.20.1-1.7.3. Thanks for the report!
