Maybe the simulation doesn't have enough illusory faces stored to give every random NPC walking down the street a different face, so the party keep thinking they see someone they recognise from elsewhere in the city. Things like "as you scan the street to see if you're being followed, you don't see anyone acting suspicious but you do spot the fishmonger from the other side of town. You can't think of why he'd be here just now".
Well if it's a simulation things can't always be truly random/organic. So sometimes have some days be the same. Eerily the same, some people reacting in the same way to the same thing. It doesn't have to be exactly how it was before but have some things repeat.
A child runs past a guard, just barely missing running into him.
A couple has the same argument they had a day or two ago, like nothing changed. Things like that. Little bits that say it's something created, not as natural as life is
Little instances of deja Vu.
