I am having some very odd problems lately with space travel times. It’s taking a much longer time than advised from the screen. For example, this morning I have made a sub light journey that should have taken about twenty minutes. The clock ticked down as normal and then when it approached zero it slowed right down and then it started to go up again, back to two minutes. A bug maybe? (It also happened in hyper, the last few hours took all day)
Yes, it affects all actions that take time. Usually, every 3 minutes your ship's location is updated. If travel is broken, this update doesn't happen, thus your ETA stays within 3 minutes of the ETA it had when travel broke.
