I encounter a glitch were on every class of vampire I played, from the 2nd power up, none of the spells were accessible from the scrolling wheel or the hot-key mapping. This happen on one of the power set for every class. After reading another report of a similar situation with the Malkavian Demention powers missing, I followed the same instructions and was eventual able to access the powers through the hot-key mapping menu, but not the scrolling wheel.
While I do not find this a problem, I just thought I should report it. I am running the game on Windows 7 with no other mod apart from a few PC re-skins, using compatibility mode "Windows XP service pack 3" and the only way I could get the game to render properly was when I installed the Camerilla edition 1.2, not just patch 6.5 I think it is. I have encountered no other glitches so far
I don't know if this information is reliant but there you go.
Hope this helps in some way.
And thank-you, thank-you, thank-you! for this mod that makes a great game, even greater!
