I have spent pretty much all day working on this and thought I had it nailed, but alas not.
Hopefully the patch tomorrow may shed some light?
For now I have the Caucasus map running. We can switch to Syria but please do not call the Persian Gulf.
I have removed the 3 Persian Gulf missions (05:45, 10:00 and 22:00) from the cycle for the time being so should not get called up when the server rolls.
