npc's that refuse to talk to you due to you being a mutant will still let you do their favor activities in your schedule. is this intended or a glitch? because i find it a little funny but i am not hesitating to take advantage of it.
It's partialy intended. If I remember correctly, NPCs ignore your mutations if you have around 30 favor with them, so you can still get them to talk to you even if you don't join the church. I will change this once I get some kind of gift system in the game.
