- Enemy escorts are a bit less prone to enthusiastically smack right into sinking freighters, killing themselves in the progress...improved their evasion algorithm.
- Completing the Advanced Tutorial by sinking the freighter and escaping the destroyer should now reliably finish the tutorial and award its achievement.
- The wall clock and stopwatch now keep updating smoothly while binoculars or a raised periscope are open. The stopwatch hand also moves smoothly in these views instead of becoming choppy or jumping forward afterward.
- Choosing Quit from the desktop main menu now saves pending progress and closes the application cleanly.
- Autosaves now preserve the last playable state instead of the death screen, and campaign save dates no longer appear twice.
- The desktop window now opens within the primary display's usable area, including multi-monitor layouts whose primary display is not at the origin.
- The periscope and AOB Recognition Trainer now fit correctly on 1920×1080 displays using 125% scaling, without unwanted scrollbars or clipped controls.
- Improved Japanese text wrapping in tutorial instructions and narrow controls, and localized previously untranslated import, delete, and dossier labels.
