Hitting a survivor who has a Tape does not progress achievement
This is about the achievement "Disarm and Dismember'. Its description reads:
"In public matches, hit 50 Survivors holding a Special Item".
It turns out that when you play Onryo, hitting any survivor carrying a tape will not progress the achievement. I had 10/50 before I started playing, and after a few games, in which I hit at least one Renato holding a tape and getting a full condemned on him in the process, I am still at 10/50.
