Hi everyone,
A small patch for V25 has just been uploaded. An issue where allies would not return from an operation under certain situations became apparent after getting a number of save files from players.
Since this was a bug of sufficient severity to render Vigilantes close to unplayable for some players, the issue was immediately fixed, rather than waiting for the V26 update.
The good news is that you won't need to re-start the game if this has happened to your allies. Just download the update, and pass in game time, and your allies will return.
