Ok so ive completed my first mission, all torps expended and only 10 rounds left in the cannon. I decide to head back to base (Keil), ive arrived there but cannot dock or end my mission, there is no little symbol to click so i can dock or refit or anything. Most fustrated now, anyone hae any ideas on how to end my mission? ive done well ive sank 72k tonnes of shipping

so want to end this mission properly. Thanks for the help.
