I upgraded from spigot 1.8.8 to pandaspigot and now the server crashes every hour or so.
on spigot everything is fine, pandaspigot.yml and paper.yml are defaults

which behaviours are more likely to cause crashes on pandaspigot than spigot?

Is it possible to add the option to disable relevant entity optimisations for compatibility and stability?

You're also running java 21 which is not the java version PandaSpigot has been compiled to, and can lead to errors like that
