I was in the overworld at my base.
I pressed F7 to turn on the spawnable surface overlay and the game crashed to Desktop.
Error received in log:

Link to full logs with crash report.
Crash report starts on L201.

Link to source file and line that caused the crash.

...and I just realized that link is on the master branch for 1.14.
master has a different import for GLStateManager:

import net.minecraft.client.renderer.GlStateManager;

whereas 1.14 imports it from:

import com.mojang.blaze3d.platform.GlStateManager;

The mod version from the logs is 1.16.1.
I suppose now I'm wondering why the mod I installed uses the 1.14 code base if the version is 1.16.1?

I downloaded this from Curseforge using this link for the specific file.

Do they have the version wrong?
Is there a better link to use for the correct version?

There is no official support for 1.15.2 yet. I made some changes and got it to work on 1.15.2. You can download it here:
