Hi guys,    
Im having trouble with campaign mission BFT08. When approaching the UTM co-ord waypoint it is telling me I am at the wrong altitude, however I am clearly at 12000. Tried this mission 3 times now with the same results :(    
I've included a screenshot, track is too large for me to attach unfortunately.    
Am i doing something wrong or is this a bug?   
Cheers,  
Si
