I don't see the bug listed but since there really isn't a central location as far as I can see I'll post mine here.
I can't seem to get my fleet to move as one.  I see a planet getting attacked, window my fleet and tell them to move together to the planet and only one of the ships will follow the command.  The rest just sit there.  I have to turn off the "move together" command and just let them all go when they're ready.  Is this a common bug or just me?
