Is this normal? (contains warp point tactics)

[Randallw]

I created a fleet and as usual opened a wormhole, the fleet pops through and then attacks an enemy homweorld in the one turn. As I am want to do I looked at the movement log. Here is where strange things happened. 2nd day the ships appear in the enemy home system, but there is no wormhole they simply materialised in the system (albeit at the edge). Not only is there no wormhole (although granted it appears on day 30) but the fleet has been divided into the original components from two turns ago. Two small fleets and a transport move in perfect synchronisation to the enemy planet. At the end they are put together into the main fleet I built. I can't remember this happening before. It's a devull game by the way.
