Especially in RSRDC, but also most other mods, and the stock game, when you radio a Status Report or Contact Report, there's a little "chance" routine that the game runs. it checks to see where you are located and if there are any Dynamic Campaign missions nearby, and what their "probability" percentage is set at. So if a mission has "within 2000km" for a parameter, and you're within 1500km, and the percentage chance says 50%, you stand a one in two chance of being assigned another mission. Some of those missions are set to 100%, some to 10%, and all the numbers between, so if you don't want to get another assignment, don't make radio contact. Either that, or just go home. I don't know of any mods that penalize you for skipping these "extra" missions.
You will find typos in the stock game, as well as all the mods. It's human nature to make mistakes. I wouldn't doubt if there weren't some erroneous assignments give with bad co-ordinates it real life also...
Follow the stars, and hope for the best
