Thank you for all the welcomes
In response to bowfin, my mate sunk 2 of the AMCs in Scapa Flow and said they had counted for him. I figured I'd hunt my last one there as time was running out. I hit her with 2 fish and watched her go beneath the waves, counting as a kill. Was so close I could ID the ship very easily. Then we move on to the carrier task group. The one carrier I needed in the specified patrol area I hit her with the last of my fish, 3 and it registered as 3 hits and a kill. Was too busy trying my best to evade to check if it had counted. Well, it showed as sunk in the logs, same as the AMC. Also received a message from command saying good work, and and all that. But now I'm past the due date for the mission and it says failed. Ok, its in the log, obviously command knows about it, I've refit enough to tell them personally, but the mission says nope. I am confused here. It has to be a bug and I'd like to know if any one knows a fix.
