I created a test world to test shaders.
Entity tick errors were constantly appearing in the chat, mostly zombies and witches, then husks. In the end, the game crashed.
This is my first experience using Neruina after the 2.0 update.
Crash-report and latest.log (I'm sorry that some of the messages are in Russian)

I know that Too many ticking exceptions is intentional. I looked that it could be disabled in config, but I don't think it's an option for me.
So I guess I should create an issue in Let Me Despawn repo.

Yes

Is my world corrupted or is it some kind of incompatibility?
I don't think I have mods that make changes to the AI of caught errorring vanilla mobs.

See https://github.com/Bawnorton/Neruina/wiki/Too-Many-Ticking-Exceptions this is intended behaviour

let me despawn is breaking.. badly
