Krell Resurrection and other problems with VC

Alright guys, currently downloading 1.4.3 and 1.4.4 to patch up, am now still on 1.4.2, but, got a question:

Now, still in 1.4.2, as Vampire Counts, conquered Brass Keep, hoping to finally get Krell. Bad thing is: Whenever I conquer Brass Keep, next round is CTD. Has that been fixed in either 1.4.3 or 1.4.4?

Another thing: Also VC, the 'hiring' of skeletons as mercenaries, one can only once in the beginning hire the skeleton spear and normal skeletons, from then on skeletons can no longer be hired, only zombies, skeleton cavalry and skeleton archers. Has that been fixed?

And last but not least: I get tired of having to modify the descr_unit every time after I patched up to rectify the weapon upgrade of the Grave Guard, the Skeleton Spears and the normal Skeletons. Has that been fixed too?

I havnt gotten to Brass keep yet (There are a crap load of Empire soldiers constantly at my gates!) but I have noticed the mercenaries bug aswell in my campaigns. And im running 1.4.4, as for the weapon upgrades and crossbowmen im not sure if its still around. Im going to look into it tomorrow.

There might be a bug with the priests and Vampire Cult religion, in fact im positive there is one. During the first turn in your starting provinces its really high, 95, 90, ect. Then on the second turn it rockets down to 65 or so and stays there regardless of how many priests are in the province, and I do put alot in there. My priests also have a really high chance of going haretic on my aswell but im not sure if thats an actual bug or really bad luck
