Re: Vampires: It was mentioned (I believe it was in Termite's Flux post pertaining to that battle) that there was an unusually high concentration of Cursed arising from the dead of the Grot battle due to chaos mumbo jumbo.
Additionally, just because you have a 1 in 100 chance of becoming a Cursed under normal circumstances, that does not mean that if 100 die then exactly 1 comes to life. In fact, the probability of getting exactly 1 Cursed from 100 dead is about one third (0.37). There is a nearly equal probability for there to be no Cursed. The remaining third of the time you would get 2 or more Cursed from 100 dead.
Also, the Grot battle is not the only place Angels have died. There are the 50 Fallen Angels which were in the horde attacking the village.
There have probably been other circumstances too where Angels have been killed, but probably only individuals so a Vampire arising from that would be unlikely, but since we are the authors of this world we exist above such constructs as chance.
