How long does it take the Strike Forces to respawn? (Assuming you are able to get rid of them).

They appear to leave for atleast 24 hours... not sure if it was the update or something like that which made them respawn or a time limit. Is that the way it should be?

mmkay, I killed all the serco strike forces and they don't appear to be respawning (for me). It's been close to 72 hours if not more than...

They're just scared. I'd be too..
