[QUOTE=czar] I guess it isn't clear what it is you are wanting to accomplish.
@czar I'm sorry, there an issue, if you see 4 units, then select one in the top (Instance 1), try to right click over behind of every other units to push (Instance 2, Instance 3 and Instance 4), it works as we expected, now deselect and select Instance 2, try to right click over behind of Instance 1, it looks like it keeps moving until stopped. Not perfect.
Now, try to select Instance 2, try to right clikc over behind Instance 3 and 4... It seems the ghost pass, it means it's not working as well... There only one working is Instance 1 after all... It makes me hard how to solve the problem.
