This is the pastebin crash log.

Minecraft v1.20.1
Forge v47.1.46 and also tested it on Forge v47.1.47
Using latest Java version.

Fixed in 0.7.1

During the day and middle of the night it works perfect. As you can see.

When pressing update, thinking a newer version after v7.1 might have been released.
The mod reverts back to 7.0a when pressing the update button in CurseForge.

Here is the picture showing the mod saying it has an update,
even though its the latest version. And when you press it to update it, it reverts back to 7.0a.
Thought you should know 🤓👍

Hey @Asek3

I also wanted to point out. At very specific times (in game time)
During Sun Rise and Sunsets
Sun Rise @ 0.00 to 0.59
and
Sunset @ 9.00 to 10.00

I get this every single time. I tried on BSL, Sildur's and Complementary Shader's, to make sure it was not the shaders themselves.

Sorry. 😢 I don't mean to bring you more headaches than you have. 😳

And these are the sunrise ones.
