What happened to patrol?

For a while now I can't set up proper patrols anymore.

For example:
If I want an air scout to patrol in a square around the enemy base, it just does not work,
it becomes an x or triangle and my plane goes over the enemy base and dies to commander AA.

Is its system changed? I just shift click with the patrol button (p) on 4 spots and expect it to to become a square.
It used to work fine during the beta.

So I guess its just me where patrols are acting up?

I think everyone just uses area patrol so if anything's up nobody saw it.

I've noticed it being funny some times, especially with air. I didn't think too much of it because area is usually better.

Anybody will to play around and test it?

I have not noticed anything too weird, other than planes stopping their patrol when they spot an enemy.
