Major instances:

• Pulled by ghost
• On rotating ball floor
• Bowser's vacuum
• Moved by knockback
• Moved by bashed scare

Side effects, in order:

• Unable to stop taking damage without letting go/unable to capture chauncey/bogmire decently
• Unable to reliably catch the floating whirlindas
• Unable to evade the attack
• Not moved away from damage source
• No ccontrolled movement

Fix?: Teleport, then wait 1 tick before the next teleport

This literally CANNOT be fixed, if your connection communication takes longer than the time between teleports, you cannot move, no matter what I do.
Let's hope Mojang tackles this issue.
