[Bug] World does not stoke block light data

[iPanic-Dev]

Issue

I mentioned this on the Discord quite some time ago, and haven't thought to come back to this until more recently I noticed my stop-gap (a script to pause the cleaning task) wasn't firing in time. Hoping to get this more permanently resolved.

My understanding is it's a compatibility issue between the forge Starlight plugin, and Lightcleaner; but I could be wrong.

Server is running Arclight 1.18.2-1.0.7, Starlight is starlight-1.0.2+forge.546ae87

Logs

I've attached a snipped of what this error looks like. I can provide full console logs, but these spam for miles so it's quite the read.

Ignore the irony of my issue title...

Hm yeah there is no support whatsoever for Starlight - the MOD. Only the paper starlight implementation. Its confusing because there are paper + forge hybrid servers which technically can do both.
