I'm playing an unarmed stealth character so i figured friend of the night would be great. having low light vision when indoors and at night would be just the thing i needed so that i wouldn't havw to use the flashlight and give myself away, but i have the perk and, while it works at night, does not seem to always work indoors. At first i thought it was just because i wasn't in low enough light, but i went into a building that had next to nothing for light and it still didn't work. Is anyone else having this issue and is it fixable?
