Replacing Torpedos

[CaptJC]

Having used all my internal torpedos I went to the weapons management menu to aquire the ones which are stored externally.I had a full complement of crew inthe forward torpedo room,the weather was calm and sunny.In the past I am sure I used drag and drop to move them into the boat but for some reason I can't shift them.The caption comes up 'In queue for loading'but nothing happens and I'm not doing anything else.Can anyone provide an explanation or maybe I'm doing something wrong! Thanks..............
