Shrink causes continuous movement NW

[ouroborus]

I tried putting together a shrink spell with Self and Shrink. The effect causes me to move at approximately a walking pace in a northwest direction for the duration of the miniaturization (from beginning of shrink animation to end of un-shrink animation. It goes so far as to push me through objects, even into thick walls and terrain if cast while up against them.
