I am getting this in the console when starting the server. Using Axiom v5.0.2 and Paper v1.21.10-93.
[13:45:04 WARN]: [AxiomPaper] "AxiomPaper v5.0.2+1.21.10" has registered a listener for org.spigotmc.event.player.PlayerSpawnLocationEvent on method "void org.incendo.cloud.bukkit.CloudBukkitListener.onPlayerLogin(org.spigotmc.event.player.PlayerSpawnLocationEvent)", but the event is Deprecated. "Listening to this event causes the player to be created early. Using the player from this event will result in undefined behavior. Prefer AsyncPlayerSpawnLocationEvent."; please notify the authors [Moulberry].```
