Memory Leak
I have a memory leak of Players and I think the culprit is com.ticxo.modelengine.api.entity.data.BukkitEntityData#asyncTracking. Tell me, is this my mistake or a mistake in ModelEngine? The screenshot was taken using ModelEngine v4.0.5. I had the same problem on ModelEngine v4.0.3, updating to ModelEngine v4.0.5 did not help.
Players often re-login to my server because it is divided into many instances of Paper, and so players often move between them
