Patrol Area always directed North on the air carrier

Hi,

I'm new to the game, but I think I've encountered an issue.

When I'm sending plane to patrol from the air carrier, the red "patrol area" is always looking north, instead of direction, where the plane is flying.

As a result, if I want to change patrol point just a little, which would usually take couple of minutes, my plane have to return to the air carrier

Is it an issue, or I miss something?

UPD: Actually, after I change the patrol point, the plane goes back to the carrier and then again to patrolling (which takes 50 minutes instead of 5), the "patrol area" is fixed.

So, the workaraound would be send where you want it to patrol, and then immedeatly change the point just a little, and it'll have the correct area. But I think the original patrol area is a bug.
