A very strange bug I just found:

I wanted to see this Lone Wolf nerf, started up a game with 2 identical characters (Except one had lone wolf). Started stabbing each other, to find....

The character WITH Lone Wolf was healed for 5 every time they got stabbed, meaning the other person actually couldn't kill them (since they only hit for 3-5 a dagger swing).
But the odd part is the other person only healed for 3 per swing.

How do identical characters heal for different amounts just because one has Lone Wolf? (Obviously it could be entirely down to the other one still have guerrilla, assuming assassins begin with that and leech). The only other difference was gender, the male healing 5 per shot the female 3... I'm sure Larian wouldn't have made gender affect leech healing though...
