Jumping under the hanging basket in Foryn Gilnith's shack in Seyda Neen depletes PC fatigue.
If one jumps directly under the basket the fatigue is depleted far beyond the normal jump fatigue cost or is used up completely. This bug will probably apply to similar objects through the game. Is probably a physics issue of some kind.
