I recently started playing PBW and decided to play simultaneous turns against the AI to see how it stacks up against turn based and I noticed a slight problem a few minuets ago. I sent a fleet of ships in to attack a planet, which they did. However they attacked the planet 17 times in one turn. My plan was for a quick attack, blow away the star bases and whatever facilities I could hit and run away. Unfortunately my ships now have zero supplies, even though they were at 2/3rds before I started fighting. My question is, is this a known problem? If it is I'm assuming it'll be patched fairly soon. In the meantime does anyone have any suggestions on how to go about avoiding it?
