I thought the game had been updated and the Pale Master was immune to sneaks now, but I just tried a build with 15 levels PM and he still got sneaked.
The module I used for testing was the "Novice to Epic Character Maker CEP Edition" I tested against the 40'th level rogue.
My char was a Sorc 9/PM 15/Blackguard 16.

Bah... I saw that it only from 1.66Beta it is fixed.
Sorry for this post, delete it if possible.
