Summary	0006044: Chains near stairs allow odd movement options for chained creatures
Description	In my current fort I have a sentry dog chained one tile away from the top of a staircase running through my fort: +++++ Z = 0 ++>++ ++C++ +++++ (C is the chain) The dog spent much of its time standing around on the stairs one Z-level below the chain, and that made sense: chains allow for a 3x3x3 movement cube, assuming there is in fact a way to reach higher and lower Z-levels. However, I noticed at one point that the dog had wandered away from the staircase on the lower Z-level which he could reach: +++++ Z = -1 ++X++ +++++ ++d++ Spatially speaking, this move is still within the radius of the chain. However, if the chain is one tile long (Chebyshev distance) then the move is not valid: for the dog to reach this position, the chain would have to stretch to three tiles length.
Steps To Reproduce	Chain a creature near a stair and wait for it to move to a logically unreachable spot.
