I have seen the same thing, but this has existed for a long time.
While playing a scenario, I have planes manually launch some TALDs. If I IMMEDIATELY attempt to have the RTB as soon as the last TALD is released, then I get some real screwy paths back to the base that often has them trying to backtrack, or go through No Nav Zones.
But, if I launch the TALDs, and I WAIT and then count off about 7-10 seconds of game time, set at the 1-second interval, then they turn as they should and create a perfect path back toward the base.
To me, it has something to do with how quickly you assign the unit to do something (like RTB) after it has just completed doing something else (like manually firing weapons).
EDIT: I might add that if you actually pause the game, and then assign the planes to RTB, then it is less likely to occur. But, if you have the planes fire their missiles and then assign the planes to RTB while the game is still running, then you have a much greater chance of this occurring.
