I'm very new to this, and a bit confused. I've finished a few patrols (8 i think) and have around 3500 renown. Date is early 1940. I'm trying to upgrade my uboat but it won't let me. I've added a deck flak gun and an emblem, but when I choose a new type of uboat, there is no way to double click (Ive tried everywhere) to choose it. Is there something I'm missing here? Thanks for any help
