Ok. I have downloaded the current version of FSUIPC and UT2 setting is at max. Although I havent been able to reproduce a situation again where AI aircraft is being send out in strange directions, AI aircraft is still lining up on the runway when I am cleared by tower to land. That is to me indicating that there is stille a problem regarding rc cummuncating with AI.Rc is using both runway 7L and R for landing ai aicraft and 7L for takeoff. The problem arises when I am being vectored to land on runway 7L. Don't no if it has anything do with the problem with ai lining up while I am about to land?
