Does anyone know why this is happening?

Occasionally, when I turn on my computer and open my modpack for the first time, the Alex's Caves emissive blocks don't work as they should until I close the game and open it again. It's not cool to see this bug and I don't know if I can figure out how to fix it. I'm not sure if another mod I have installed can cause this problem.

Update: This error seems to appear not necessarily when you just start the computer, it appears in random startups of the game, the log I share below is of a startup in which the emissive lights did not work.

Using recourcepacks, I managed to fix the issue by using a different parent model for partial emissive textures on blocks.

I'm interested to know exactly how you solved it, could you tell me what resource pack you added?

Been having the issue as well, could never point out what it is. It's mostly notable with the uranium ore block, never happens with mobs, It's possibly a mod incompatibility..

Exactly, the problem is most noticeable in the uranium ore block and coprolight peering. I know it's just an aesthetic bug, but it still ruins the experience of exploring those caves. I hope someone can figure out what mod or something else could be causing this bug with the log I shared.

By setting the faces that are supposed to glow with "forge_data": {"block_light": 12}
AC Emissive Fix.zip
Now the genuine question is why was that not the default in the first place. 💀

Thank you very much! 👍
Hopefully this solution can be in the base mod.
