1Z [unit movment error] Peasants vanish after moving them to them selves [FIXED]

Chain of events:

I moved the two new units from the city to my Sov. I then selected my Sov army (now consisting of three units) selecting 1 of the units on the end I then right clicked on the units on the map, the unit selected vanishes. This is repeatable (until you run out of units)

in short, moving a unit to an army he is allready in makes him devide by zero and get sucked into a black hole.
