After playing the game for a while (which is great btw), I have a problem with ships and fleet changing destination without my knowledge: when selecting another ship or fleet, it doesn't deselect the first one and I have ships and fleets going where I didn't tell them to go. One way I was able to replicate the problem is when I have fleets and/or ships stacked on top of each other and I decide to select another ship at another location and give it a new destination; the stacked ships that were shown to me before in the display get also redirected there too even if they are not selected. Another way to replicate this was also when you start a turn, you have a ship selected but you decide to move another instead; most of the time the first will will start to move to the new destination selected for the second ship.
