HM well that is not new have seen that from the beginning in beta 1 through to beta 3 I kinda wonder if the builders of the game have for the beta turned off the movement of them for some starnge reason as to why well I gave up trying to think along those lines when I first started building REALLY REALLY HARD custom maps to test for being worth rating from 1 a easy map to 10 you have to be really skilled or carzy to beat in under 8 to 10 hours

and by the way I do do the up to 20 for a UNFAIR map that has been stacked against the player and or players so that they have to use their minds to beat the AI or other players on the maps it's self because the way I think of it If it was easy well then why would space be considered the last fronter to build and live in

In all of my games so far all of these ships move. I just build a few refineries, and the ships moved right on to nearest asteroids. I have noticed though, that ships seem to bump into eachother more when they are lining up for a jump, maybe this is related?

I get this problem particularly in late games, it's a little annoying cause it's nice to see all your worker bees buzzing around your empire.  But on a more gameplay oriented side, it also stops you from being able to hunt down the enemies for quick credits.
