Are the "Wanted" posters bugged for a High Chaos Ghost run?

So I'm currently playing my way through being brutally murderous, but also making sure I get that Ghost tick at the end of each mission. I remember when doing a previous Ghost, non-lethal playthrough seeing "Wanted" posters around Dunwall, saying that an unknown person had eliminated targets from previous missions. On the poster, there would be a question mark as to what this mysterious assailant looked like.

This time though, I noticed on the Golden Cat mission that the Wanted posters had a picture of the "masked felon" who had killed High Overseer Campbell. In later missions, other Wanted posters showed Corvo's mask and named the masked felon responsible for eliminating the key figures of the city. Surely, because I made sure I got the Ghost tick at the end of each mission, there should be no masked face on these posters?

Is it possible that because I talked to civilians, like Granny Rags and Griff, that don't cause you to lose Ghost status that Corvo's masked face is now known by some in Dunwall, and so the game thinks it should go on the Wanted posters? Or maybe the Weepers in the sewers between missions saw me and I didn't realise it?

Of course, I won't know at the end of the game if it was a truly Ghost run, as I've already unlocked the achievement.

It doesn't matter how you do the missions, sometimes the wanted posters bug. During one playthrough I first had "masked felon" and on the next mission they were "unknown assailant".

Ah right, well that's that. I guess there are so many variables going on that they're bound to bug out at times.

I don't think they are bugs. I've noticed that even when I have deleted all my game saves that when going to the BW DLC's I am still offered either a low or high chaos start. I think they simply randomize per game stage after a couple of play throughs. Though this is just my speculation.
