Character boosted an old Warlock to try different game style in Renegades, but the tactical, Renegades ability doesn't' work; my Warlock shows no "stack" of abilities at the start, nor when looting an abilities crate. Activating the ability works, with the coin toss noise and coin flip graphics, but get no option to use, no change in abilities on the HUD, and melee buttons just perform normal actions.
