I can't imagine that this was intentional, so I'm posting it as a bug report.
The starting units on the WWII map have been changed. Germany, USA, and UK are missing ships. I checked the units by using map#40005 to create a scenario and it clearly shows that the ships are not selected to appear on the drop. Additionally, some territories (England, Western USA, and probably others) no longer have a sea zone designated. There are probably other changes too but those are the most glaring. I know changes have been made intentionally in the past, but they were subtle and done to balance play. These changes are drastic which leads me to believe there is a bug involved.
