I'm unable to get my fleets to move in DA (I've updated to the latest version, 1.80g) - what happens is as soon as I try and send a fleet anywhere further than it can move in 1 turn, it's speed drops to 0, and it refuses to move (unless I then click somewhere it can move to in 1 turn). I've experienced this in the campaign part of the game, in both the first mission, and the second mission so far, and it's driving me mad - is there any way I can avoid this problem?
