To the geometry situation, on my setup, it comes back to its original position when "undo" is clicked twice. At first glance, I though the order of operations was, somehow, mixed up ("create geometry" then "move", when undone, becomes "delete geometry" then "move back"). However, upon further reflection, maybe that first undo shows a step that was not meant to be seen by the end-user? Especially since that extra undo brings the behavior to what is to be expected. Either way, definitely a bug. It will be fixed in the next broken version
