Anyone able to help me get access to the final Skull Quest? I am currently stuck at 925/930. As far as I can determine, I'm only missing two skulls from Night City:
The Banshee (Normal) - Win with 100% Health
Lord of the Flies (Madness) - Use only Assassin characters

These two have been driving me crazy... but even that being said, I have no idea where to go to get the final 3 Skulls. I've attained a 3 Skull rating on all of my Skull Quests. Is there someplace else where I can get Skulls?
