I just loaded up a game I've been playing for the last few nights. After an abnormally long loading time the first thing that came up was an AI requesting help because they are being attacked. Then I got the usual Tech window and homeworld windows. The first fleet I had that needed movement orders I instructed to attack an enemy planet that is defended. After defeating the fleet around the world when the game brought me back to the main game screen the fleet stats window said I had 13 out of 10 movement points left. And this is after the fleet had moved 8 spaces before attacking. And the game did allow me to move all 13 squares.

The next fleet became active needing movement orders. This one started out 10 / 10 but after moving a couple of squares and attacking an enemy ship it jumped to 15 / 10 squares. I'm not sure even where to begin as far as trying to describe the entire universe as it stands. This has been a game like I said that I've been playing for several nights on a huge map. I know I've researched up to Warp V engines but the ships in question only have I think Warp IIIs. Also I've built Hyperion Shipyard and the Gravity Accelerators. I do have a couple of fleets that have mixed base speeds as far as the ships they contain but neither of the fleets that exhibited this behavior are mixed. I do have a couple of ships built that have base movement of 15.
