I recently changed alliance and moved my units from one side of the country to the other. Now I have calls on the other side of the country that appear to be stuck and I am not getting any new missions. Not sure how I can resolve this issue.
The missions will despawn 48hrs after they was generated. If your at you max number of missions then you will have to wait the 48hrs, coin them (waste of coins) or see if an allaince member can clear them if there is someone in your old area.
