I have a question for anyone attempting to use v1.46 or the Preview: Have any of you attempted to purchase an early radar? Did it function correctly? We already know that the ST radar needs not just the mount for the radar, but also a new periscope and periscope mount in the conning tower, which is why a person cannot purchase it early, because it is a two-part "upgrade", and the game only allows purchasing one part at a time. I am curious though about an SJ or SD radar purchases, if they function correctly? Thanks
