Minecraft version: 1.12.2
Wizardry version: 4.3.3
Environment: Server

Issue details: When I try to upgrade my armour on my server it throws the exception linked in pastebin (this is not a crash), it works as expected in single player and lan worlds. This issue also happens on another server with this modpack and to other players.

I will try to find the problem mod later today.
