PS3 player, so no mods for me. but i actually got more into the game again after actually creating a new character with a backstory and playing some Dead is Dead challenges.
after killing mercer and becoming a nightingale brynjolf doesn't ''have time to talk'', though i have no idea why delvin and vex aren't talking to you, since they always seem to give away some extra jobs. i guess i can't help you then.
