Forge version:
Twilight Forest version: (twilightforest-1.12.2-3.11.1021)

Steps to reproduce:
Install last version of Twilight Forest for 1.12.2

What I expected to happen:
Texture of Trollstein block should become brighter under the sun.

works fine in 1.16 versions, so im closing this

This World check in getActualState is no good for rendering:

Probably not relevant in 1.16.x though.
