I was playin a game in 1.12 and I had a fleet with the rapture and the halycon. I told the rapture to go to a terran planet on the other side of the wormhole and I didnt watch it cause I was busy with other stuff. Then I checked on its progress of clearing out the terran and the halycon wasnt there but rather flying across the system AT REGULAR speed. I didnt notice it till it was like a third the way there and told it to go back. It took a long time.
