Similar thing in PeL recently. Our last Banker was stabbed. Realm got a message that he was seriously wounded, and the infiltrator collected the bounty. In the same turn he left for BT. Apparently the new wounding system left him with only light wounds. It would seem that the new wounding system and the old are both in play in different places.
I actually saw the infil's message on that one. There was extra text after the "put him down for good" part, something like "you see him start walking as you escape" indicating he insta-healed from serious to healing.
