Describe the bug

Copycats emit light properly when copying light emissive blocks in version 2.05, but stop emitting light when upgrading to versions 2.10 and above.
Further, new copycats placed under v 2.10 and above do not emit light.

To Reproduce

Using modded minecraft loaded with copycats-plus versions 2.10, 2.11, or 2.12:

1. place copycat
2. click on copycat with light emissive block
3. observe error: copycat does not emit light

Expected behavior

Copycat should emit light.

Screenshots

First screenshot, using version 2.05: copycats emit light

Second screenshot, using version 2.10: copycats do not emit light

Desktop (please complete the following information):

• Minecraft Version: 1.19.2
• Mod Loader: Forge
• Mod Version: 2.10, 2.11, 2.12

Additional context

Again, copycats emit light properly using version 2.05

Please make sure that you don't have Starlight installed. Light emission before v2.1 was client-side only and was usually lost after you restart your game. Since v2.1, we have an experimental fix for the issue but it isn't compatible with Starlight.

Thanks for the idea. I don't have Starlight and have never used it.

Are there other mods that cause the same effect?

The strange thing is that I have the opposite problem of most users--light emission worked fine in 2.05 for me, and stopped working in 2.10 with the fix. Staying on 2.05 is a reasonable solution; I was just hoping to make use of the new fixes and features of 2.10+.

We have implemented a more proper fix in Copycats+ v2.1.3 which should hopefully solve all lighting issues for now. However, this issue is more deep-rooted and will require an update from mod loaders to completely fix.
