I'm playing through AC2 for the first time, and I started it up earlier and found out that I'd somehow lost a pretty significant amount of progress. I had been in Venice, but now I've been bumped back to the middle of the assassin tomb in Forlì. I'm not too upset, and I guess now I get to re-play the part with the Leonardo hug, but...so many side-quests to replay! Has this happened to anyone else?

Anyway, my prompt.
I'd like to see a description of the last few minutes of a guard's life before they get stabbed in the back/front by Altair's or Ezio's hidden blade, and/or what the courtesans think about That Weird Guy who hires them all the time but doesn't ask them to do anything but follow him around and flirt with the guards.
