The tooltip of a fleet shows the number of moves left for the fleet. This will randomly disappear. The only solutions is to exit to desktop and load the game again. I noticed this in 1.0 two or three times. But now that I have 1.01 I already had it five times in two turns. I do not know what pattern there is to what causes it because it is not certain it did happen in my previous action already. I will see what my last actions were (attacking a pirate I believe the last time), maybe other can see a pattern.
Not knowing the number of movement points left or having to restart twice a turn makes the game unplayable for me, so I hope this can get some priority.
Edit: Hit points are also not shown when I hover over the individual ships.
