Well, now you have the ability to edit the proper file to make sure that all information is possible and properly formatted, omitting the names of submarines and captains.
It would be a great project to research the entire list and find the other "errors" (which are not errors. Ducimus was simply supplying historical context for your gameplay), substitute factual or at least plausible messages, which should all be broadcast from your sub's originating base. I'd suggest replacing all submarine names with their radio call signs (however you might come up with that information.
Subsowespac.org might be able to help you with that!
If you are inclined to do this pretty intimidating project, it's pretty easy to figure out the format of the file. It would be really easy to make your version into a mod to be added on top of TMO. If you need help with that I'd be glad to help.
Spoiler alert! However, the way the game is hard-wired, it is entirely possible that you would receive a report from CINCPAC that the Yamato has been sunk and then encounter the Yamato later that afternoon....... Help! The space-time continuum is BROKEN!
