AI formation leader gets stuck

I just saw the silliest battle between a big Ukra fleet and a single Krill torpedo ship. The Ukra formation leader got stuck between my planet and the dozen or so yard bases around it. The whole formation stalled out of range while the Krill ship torpedoed them at leisure. They had PD so nobody got hurt though. The point is that the AI formation leader needs to learn how to backup when blocked, or better yet not get blocked by planets/bases in the first place.
Anybody else see something like this happen ?
