Hey
Fabric 1.20.1
I crashed when lightning struck my glider with the copper upgrade.

Interesting, when does this occur?

The crash only occurs with the copper upgrade.
The crash occurs when lightning strikes me.

I tested the copper upgrade with both the Netherite and diamond gliders. In both cases, the game crashes when lightning strikes me.
So the issue arises from the copper upgrade.

Fixed
