Just discovered a weird, but unfortunately game busting glitch in Diplomacy 1.21. When you build a fleet and leave it to its own devices in a gravity well the whole fleet 'wanders off' into deep space (moves out of the gravity well). I've notice this happening about mid game when large fleets of 350-400 supply or bigger are built. The fleet can usually be found loitering somewhere on the map. When ordered to move they just stay quite happily in deep space and never return to a gravity well! This is frustrating as it means that your fleet capacity is technically crippled. Any ideas what causes this and why? By the way Entrenchment runs fine without this problem.
