Teleporting player outside level coordinates crashes the server #13186
Description
Stack trace
teleportAsync(): https://mclo.gs/bu9wHY1
teleport(): https://mclo.gs/kwRYdYq
Plugin and Datapack List
@EventHandler(ignoreCancelled = true)
public void onAsyncChat(AsyncChatEvent event) {
var player = event.getPlayer();
var location = player.getLocation().add(0, 0, 100000000);
if (event.signedMessage().message().contains("1")) {
player.teleportAsync(location);
return;
}
if (event.signedMessage().message().contains("2")) {
getServer().getScheduler().runTask(this, () -> player.teleport(location));
}
}Actions to reproduce (if known)
See code above. Note that after teleporting the player on the main thread and restarting the server, the server soft locks if the player joins (seen below). This doesn't happen if the teleport is done async.
