Minecraft Version

1.21.1

Immersive Engineering Version

ImmersiveEngineering-1.21.1-12.2.0-187

Expected Behavior

When I remove a shader from the revolver, chem thrower, railgun, saw, drill, or heavy shield, the shader will be unequipped and the texture for the tool will return to default.

Actual Behavior

When I equipped a shader to all six tools and tried to take it off, not only did removing the shader not change the tool back to normal, exiting the Engineer's Workbench and re-entering it revealed an identical shader was still equipped on the tool, allowing me to generate infinite copies of the same shader.

Steps to reproduce

1. Place tool (revolver, chem thrower, railgun, saw, drill, or heavy shield) in engineer's workbench.
2. Place shader in tool's shader slot.
3. Remove shader, notice tool has not changed to default texture.
4. Exit workbench and re-enter.
5. Notice new shader has appeared in shader slot.
