Version: 5.0.2 - ResourcefulLib Version: 2.1.16

I'm developing my own mod that interacts with this one and I've noticed some textures are missing.

Crystal Chest:

Obsidian Chest:

Console:

[01:08:41] [Render thread/WARN] (Minecraft) Failed to load texture: ironchests:textures/gui/chests/diamond.png
 java.io.FileNotFoundException: ironchests:textures/gui/chests/diamond.png

make sure your config folder does not contain files from previous mc versions

ok this fixed everything, tysm

Ill pin this for others that may run into it
