For number three, check the places she's usually found in, and talk to people! Fawn will only appear up there when the game tells you she's there.
I'll fix that bug!
Speaking of Fawn and Upper New Ark, She goes to classes every other day and I'm kinda tired of my character waking up to an empty doubles unit, any chance you could add a command or something that allows you to decrease that frequency?
Along with this, Is it a bug that Fawn still goes to school whwn you get her preggers? From what I understand thru reading her talk dialogue, Fawn is concerned that going to work and school might be too much for the bun in her oven.
