On occasion when I load my game up, my ships forget that they have any range at all. I mean, I could launch a ship from one of my planets, and it wouldn't be able to move. Right now in my game I'm trying to bait a full fleet away from my home world with a sentry, but the ship can't move, it'll die where its at without buyin me any time at this rate. I think maybe it fixed itself once before when it happened after I reloaded a few times, but I tried that three times and it didn't work this time so I figured I'd post before I went back to piddling around with it.
