Power Word Sleep issues

Vreejack

After some experimentation I have found that there is definitely something amiss with power word sleep.
Whenever it is successfully cast the proper "unconscious" affect is applied to the target, and the fall animation plays, but the target will then get back up for the rest of the turn (and will pursue you) before falling again and apparently staying that way.
You will get one free strike against the unconscious target, but this will apparently awaken it. This is unlike other sleep effects like color spray, which allow you to attack repeatedly for free for the entire duration of the spell.
Sometimes, even after you "awaken" a target with a hit, it will briefly display the falling animation before attacking you, suggesting that the engine knows the creature is still supposed to be unconscious.

Here's another odd example. I PWS's Greywolf (Prism quest) after blinding him and working his hp's down. I never got a free attack, per se (all were rolled), but he never attacked me again despite standing up like he meant business and despite the fact that it probably took me another twenty turns to kill him.
Edit: he never attacked me again because he was blind and out of reach.

It appears that power word: sleep and color spray use two different functions for what is supposed to be the same status, and this why their results are inconsistent. PSW victims will wake up on a hit.
