Additional Bug: Impossible to complete Geth Incursion missions due to Bug on planet Rayingri:
Geth Drop ship becomes stuck in the sky above the overrun base. It doesn't spawn additional enemies and also does not leave, preventing the mission from completing.
Leaving and coming back, reloading prior saves, and relaunching the game all have not solved the issue.
I just killed the ship. Problem solved. Shoot at it with the Mako.
Been shooting at it for 5 minutes....it doesn't explode in this bug apparently.
A similar thing happened to me, although I did somehow get the mission to show as completed.
After you deal with the husks and consoles or whatever it is in the backroom, you go back to the entrance in order to leave the base. At that point there's more Geth in the main chamber. I got killed at that point, so I reloaded my quick save. Once I did that there were suddenly no Geth to be seen in the main room and I was able to leave the base like that.
The dropship definitely doesn't disappear; since when I revisited Rayingri later to get resources (I left that for the end), it was still hovering above the base.
