When I send two squads at the same target and delay one and not the other, they show up as a two squad group when I hover the mouse over them on the map - as though they were a group of squads that had the same ETA.
The confusion clears itself up the next tic when the first squad moves ahead of the delayed one, so this is not one of the more serious flaws.
btw, first time using photobucket so let me know whether or not clicking on the image below makes it full size or not, ok? Thanks. If there is a better method of linking pictures/better picture sharing site let me know.
