Idk what the deal is, I cant do heavy attacks unless its on npcs apparently with the talk button e_e
What are you playing on? Kinda assumed Xbox since you said A button but just checking.
pc with an xbox controller, I dont see anyway to remap the buttons to controller.. i didnt change them at all and the right trigger used to do heavy attacks but trigger does nothing now and I keep attacking npcs without doing anything >.> pretty sure i cant even go on now because the fat guy and the blacksmith both wont let me by
You don't need to go down there for a while... if you haven't yet go back up to the church and then to the top for a boss fight, after that you can ring the bell and when you climb back down there will be a npc with his arms spread at the bottom of the tower. Ask him for absolution and when you pay him the black smith should no longer be hostile....
As for the trigger being weird I'm not sure on that.
