Yeah I know what you meant. Go click the Quest tab.. Above the chronos/divine tab.. the icon is a sword.. Now find and click that persian mission, its like you have to start it.. Go attack and kill the persian position.. repeat every time.
If this doesnt work.. You actually do have a bug - a wierd one.
Hi missy
To unblock new mission there are 2 requirements:
- reach persian position requirement
- go on quests tab and clic to finish current mission request, and afterwards clic on new mission tab. The mission will look something like this with different name depending on your mission lvl.

reload game and then you should have new one..
If this does not work could you please post a screen of your mission tab
