Prerequisites

• I am running the latest alpha version of MineColonies and Structurize for my Minecraft version.
• I checked the MineColonies/Structurize wiki and made sure my issue is not covered there.
• I made sure that this issue is not a duplicate of any existing issue.

Context

• Minecraft Version:1.16.3
• MineColonies Version:0.13.380-ALPHA
• Structurize Version:0.13.92-ALPHA
• Related Mods and their Versions:

Expected behavior

When I speak with my stonesmelter, it should open his UI thingy.

Actual behavior

After I right click on him, I can see the black chat window thingy, where I can skip the chit-chat and the other 3 options. Then, I should see his stats, but it's all blank, and the game also freezes in the meantime, than it crashes.

Steps to reproduce the issue

1. Right click on the stonesmelter NPC when he is in need of something (like coal or etc.)
2. Click on 1 of the 4 avaliable options.
3. The game crashes.
