I'm currently playing Project Ozone 2 (2.3.0) and encountered the mentioned issue.

You can reproduce it by /giving yourself the wireless crafting table (WCT) and then eg. /giving yourself a piece of dirt. Doesn't matter if the WCT is inside your inventory or in your hotbar.

This will crash the game and further prevent you from loading the world without deleting the WCT from your inventory with a NBT editor.

What's super strange though, is that when I try to reproduce it in a test world. If you first move the WCT inside your inventory and back to the hotbar, it no longer crashes. But this won't work in my main world.

I first encountered it when shift+right-clicking a Bibliocraft clipboard, which drops it as an item.

Happens with PO2's default 1.7.10-rv3-1.8.7.4b and the newest 1.7.10-rv3-1.8.7.9b
