I'm running along when suddenly I zone out the exit of a mission area long before I actually make it to the exit door. Likewise, I've been pre-zoning from one outdoor area to another.

This sort of thing has happened to me before, but it's been happening a LOT since the latest patch.

As an aside, I also noticed that Rome was REALLY screwed up last night. Zone doors didn't work. Areas were missing. Could have been just my client and not the server - don't know.
