Spigot 1.16.2 server crash and hangs

[Tsoccerguy3]

latest.zip

I issued /cleanlight command using the new BKCommonLib-1.16.2-v1-SNAPSHOT with the LightCleaner-1.16.1-v2-SNAPSHOT . this sometimes crashes the server , but not always

[bergerkiller]

Looks like a loop trying to load chunks, will look into it

The plugin snapshots for bkcommonlib are a bit unstable as I was making very large internal changes. Can you check using the latest 1.16.2 bkc build? (yes, it supports 1.16.1) https://ci.mg-dev.eu/job/BKCommonLib/867/

tested and no error

I think I've found and fixed the server crash you've encountered, see if it's better now. Also fixes slabs/stairs letting light through.
