I had this problem with my Fortunata shortly before i17 went live, only it was with Tsoo Sorcerers. No matter how many I killed, the counter never started. What finally did it for me was joining a team and having one of my teammates kill one. At that point, the counter not only appeared, but it had several kills already accumulated. The server is probably keeping track of the number of witches you dispatched, but for some reason the badge counter isn't showing up. Join a team and have someone pop a few for you, and if that doesn't work, try a Katie Hannon TF. Maybe triggering the system into TF mode will wake it up (my bar appeared on the first mission of a Silver Mantis SF).
Seems no matter how many cabals I kill I don't get the count started for this badge.
Is it still valid? Am I killing the wrong type perhaps?
thanks in advance!
