Hello fellow developers,

After some debugging we have experienced many server crashes with reason: Java heap space
We have generated heap report and seems like we have way too many chunks loaded.
Is there a way to tweak this LightingFeature from our side besides forking and removing this feature ?
Seems like starlight in 1.18.1 uses way to much RAM by loading chunks that are not unloaded then
