Did you rebuild your bashed patch if you are using one?
No, guess I will try that thanks.
were you also using Ambient Dungeons? the two together can get very dark, and AD does NOT affect NPC's detection.
Yes, using both.
Edit: Yeah tried disabling ambient dungeons, seems like ambient dungeons makes dungeons very dark on it's own, so I'm pretty sure I uninstalled Let There Be Darkness fine now and just didn't realize how dark ambient dungeons made things.
/facepalm @ myself.
