Hello,
I play SP, and had this kind of problem few times already...
If for some reason I am out of the Area of Operation, and close a task, the mission ends and I can not complete the other tasks...
For example, I was playing with 3 objectives, then I would have to join Alpha team to conquest st.julien...
Well, it happened that the captive I was looking for as last task, was out of the Area of Operation, so, as I untied him, automatically I ended the Locate, Free and Extract tasks all at once, then the system create the Join Alpha task as expected, but no way I could continue, the mission ended there, as, I suppose, I was out of the area of operation... this happened also, for example, if I have to steal a vehicle and bring it out of the Area of operation, as I exit the Area, the task completes and the mission ends, and I have no way to continue the other tasks...
Any way to fix this...?

thanks

Alex
