I noticed in the parkour that when you finish, you have to die or if you fall you die. A Suggestion I have is to use multiverse portals to teleport players back up to the spawn area when they fall so the players are less stressed and its quicker. And some players (Myself included) have a glitch where if there is a lag spike we are stuck on the death screen for 5 seconds after clicking respawn. The multiverse portal can solve this. And for winners, you can add a command to the server signs plugin to teleport them back to spawn so players wont die in parkour every time they fail. Edit: You should also disable fall damage that can kick people off of the parkour course.
