Game needs some changes. I invaded europe and took Cherbourg, and Brest. I had control of Eastern Atlantic with a Carrier battle group, and i had the Channel with another Carrier battle group. I had 92 smp's, and 20 strategic points.
After getting well established and moving east on Germany, the supply comes up "failure", and of course troops are at halved. The next turn, same thing, failure of supply, even though both Cherbourg and Brest are open!
When a lone enemy ship can move into a sea zone with a carrier battle group protecting the shipping lanes, and cause a failure, somethings wrong!
