undo move post overrun

I think this is straight forward but I can supply screenshot and other details if needed.

Barbarossa quick start scenario - I did an overrun and then continued on to next clear space (with the ge arm hq and an arm). i then dropped hq and moved arm another space. Then moved some other units. Then right click and chose undo on hq - that worked but it wouldn't let me move it afterwards, back to the space it just came from or other.
