Every time I start my SkyBlock server it works fine but then in a few hours, it crashes. Any help would be great!

Basically its saying that there is an entity in the game that the server does not know of. What kind of plugin are you using? And have you downgraded the jar file? If you have not, then it could be an entity is spawning that the server does now know what to do with, therefore it crashes.
