A few changes that will effect how players gather evidence...
With the last update I introduced "sightseers" in the tabloids. In these cases, it was not an incident that occurred in the city itself, but someone in that city was out on vacation when they encountered the "thing."
So in these cases, the tabloid gave some evidence as to the location of the city in question. However, this has now been changed.
Sight-Seers and City Specific Evidence
The tabloids of this type are now very general, talking about a person on a drive or visiting friends, with no information about the city being visited. However, if you are able to send a team to interview the holiday goer, and it turns out to be a real headline, the specifics will now appear in the report and be shown under "evidence" instead of "tabloid" in the city folder.
It adds a bit more complexity to the game, and also changes how some aberrations might be discovered. The main difference between this kind of evidence and other types, is that it could appear anywhere on the map, not necessarily near to an aberration. It also (I think) makes the game world a bit more self consistent, where the tabloid headline will influence the kind of evidence you can gather.
City-specific evidence like this can be categorized by approximate location on the map, population, longitude/latitude, year founded or even the name of the city itself (rare). When you are able to identify a few of these kinds of witnesses, it can make it much easier to narrow down the exact location of an aberration.
The additional change is that when interviewing travelers, your team is not in as risky a situation, so they are far less likely to get ambushed. But always take precautions! The tabloid itself could be fake, and just happen to be in an aberration city. There is always risk :)
