every time you try

Hello, I've tried to replicate the bug in 1.18 as I am not supporting snapshots.
The bug appears to be manifesting only when trying to upgrade a vanilla chest to a copper chest.

Thanks for reporting it!

IronChests relies on the ChestBlockEntity class.
This with the 1.18 update has made the writeNbt method protected (previously public). As I cannot cast the ChestBlockEntity into a GenericChestEntity class. (Technically can avoid this, but the content of the chest would be lost in an upgrade)
I won't work on reintegrating the Wood to Copper upgrade yet, as Mojang might change that method again (as it happened with the last 3 updates.
I am pushing an update to disable the Wood to Copper Upgrade so that it doesn't throw an error.
The item will remain with a [WIP] warning until I find a fix. Players will be able to uncraft it if they have a mod that allows so.
