When you double-jump after joining parkour mode while flying in air prior, you get an initial boost from the flying until it then disables the flight state. Would it be possible to force disable flight when joining parkour mode rather than wait until it detects a player is trying to fly? So they don't get an initial double-jump super-jump.

Not entirely sure of how to recreate this.
Is the player survival when they join a course?
I've done a minor change to disallow flying when you join a course, but it already disabled flying if you already were?

Yes, it is when a player has flight mode enabled and they join when in survival mode, flying in the air prior. Not joining from a ground position. It is as if flight mode is still enabled when they get put in parkour and they are allowed to fly up a block in height before it detects and disables.
