Hey there,

I'm the author of Universal Tweaks and can assure that the Entity Desync functionality was improved to no longer cull Immersive Vehicles' entities.

The implemented warning can be safely removed now:

Rodger that. Thanks for letting me know! I'm honestly not surprised that your mod culled the entities since they have some funky logic in them to prevent MC's default shenanigans from occurring. Will remove that notice on the next relese!

Addressed in 22.16.0.
