It can be fixed easily, however, I doubt that it's worth the effort. For instance, I just checked for the Black Swan: There are only four entries that are affected (among the few thousand ships). If you meet this group of four ships in 1943, just be happy and imagine their radar is out-of-order

Edit: I doubt that any player would ever realize whether he plays with a fixed or not-fixed version.
