DH runs into an error on server startup and crashes

Hi, I have a Minecraft server with around 250 mods installed. I added Distant Horizons a couple of days ago and it was working perfectly fine. Fast forward to today and I am now getting the following error when I try to join the server: net.minecraft.world.level.chunk.MissingPaletteEntryException: Missing Palette entry for index <the index value varies> I have no idea what happened since everything was working fine. And the weird thing is, sometimes I don't get the error and other times I do. For example if I update a mod or change something (like disable a mod and then re-enable) I will be able to enter the server. But after exiting and trying to rejoin, the error occurs again. This is happening to everyone that tries to join the server. The reason why I narrowed it down to DH is because the error being thrown about the missing palette entry is coming from DH according to the logs starting from line 3541:
[02Aug2025 08:31:05.272] [DH-PriorityTaskPicker Thread[13]/ERROR] [DistantHorizons-com.seibel.distanthorizons.core.generation.DhLightingEngine/]: Unexpected lighting issue for center chunk: C[202,-90]
net.minecraft.world.level.chunk.MissingPaletteEntryException: Missing Palette entry for index 133.

I would guess some mod compat issue Though is it happens semi-randomly it will be hard to pin point the cause !binary is probably the best bet

Try a binary search and figure out which mod is causing it. So disable half of the mods, see if issue is still there, if yes disable half again etc etc until you find the mod that's causing the issue.

I think when adding some mod, some chunks became corrupted. Unfortunate. Doesn't seem like it's a DH error after all. My bad. Thanks for the help anyways 🙂 Keep up the awesome work
