Something I've noticed in my recent game that the turn button does not highlight as it once did. It does turn green. However before v1.31 if there was any ship or fleet in the empire that had movement points left but no active destination the turn button would be active but not green. The button still changes to "Skip" if a ship reaches its intended destination with movement points left. The game ignores in terms of the turn button any ship that starts a turn with full movement but no orders to move. Also these fleets were not set to guard or sentry. Now maybe I missed an option setting change that invokes this behavior but I did look through the options screen and didn't see anything obvious. Not a show stopper but I did rely on this feature to keep track of my extensive fleets .
