I encountered an odd bug with vitality transfer. I initiated a TAKE <patient> ALL QUICK, then also tried to take his vitality loss. The vitality transfer produced this result:

<<>take lemb vit quick
<You touch Lemb.
<You are already have an active transfer with Lemb for that body part.>>

However, there was no vitality transfer taking place. Once the TAKE ALL finished, I successfully started a quick vitality transfer, but it only moved a tiny portion of vitality on each transfer pulse (2% of my vitality at a time, I think it's usually like 10% or so). I have 823 ranks of Empathy and was under the effect of a max-mana Gift of Life.
