Hi there,
first post but since I am playing beta sins I thought I add something. On several occasions I noticed that grouped phase jumping is not working as intended. It happens when a fleet forms a line to cross the gravity well only the first ship manages to jump away,the others cannot open the jump portal beacuse the first ship is in the way. They then abort the jumping process and issue move orders.
It happened to a small fleet with 4 Krosovs but also to a fleet where a single Akkan BC jumped into an enemy grav well alone 
I thought I had taken some screenies of this, but unfortunately I cannot find them anymore 
I hope the description helps a bit. Overall a very nice expansion for defensively playing spacecowboys like me
