error when kicking a player

Im making a plugin called WTF which basically adds "glitches" to minecraft to troll friends.

one of the "glitches" basically adds a 1/20 chance that the player will be kicked when the get off a vehicle.

the kicking works but i get the following error and i cant join back in my test server when i get kicked (took too long to log in error)

Could not pass event VehicleExitEvent to WTF v1.0-SNAPSHOT

Are you trying to kick them from an async thread?
If so...

Code:

Bukkit.getScheduler().runTask(...)

 

Maybe it should be marked as such then

 

Confused ,_,
https://hub.spigotmc.org/javadocs/s...-org.bukkit.plugin.Plugin-java.lang.Runnable-
Isn't...
And BukkitRunnable uses the same scheduler, just seems to be a more thread safe wrapper for a BukkitTask

Edit: Imma take a nap, I've been wrong enough for one day LOL
