I found an unusual problem pertaining to blood slaves in a battle today as Jotunheim.
My opponent attacked a castle where I had a small number of troops, but I was still able to break the siege. I got a funny looking battle report:

It shows actually negative losses for my regular troops! I didn't use any hellbind heart, etc. I didn't lose many troops, but I did lose some.
I also have a strange problem:

Some of my blood slaves seem to have been converted into normal units. I believe the mage that entered the battle with those slaves died during the battle, but I'm not 100% sure; I had several blood mages and lots of things died. They're shown here under the command of my Skratti but in reality after the battle they were in the province garrison.
Can I convert them back to normal blood slaves somehow?
