Maybe the option to enable all terrorists have something to do with that?

Not exactly that but you caused me to check that function again that creates Carmen's terrorist counter and guess what I found...

Well, the function was not changed but it assumes that all terrorists are placed randomly across the map. All randomly placed terrorist add to a counter and this counter is given to Carmen. In the current MercProfiles.xml two terrorist are preplaced, MoM and Tiffany.

So the game goes through this list:
Elgin is always there +1
Slay +1
MoM preplaced, skip
Imposter +1
Tiffany preplaced, skip
T-Rex +1

We end with the counter at 4. When you killed 4 terrorists the quest is done. This is probably what happened to E1vS.

How to solve that? We could simply assume that the data in MercProfiles.xml is valid and end with several terrorist in the same sector or a terrorist in an inaccessible sector.

Need to think about that and implement a solution.
