4. Select both naval units - confirm with F11 shows no available port to move to

5. Hit Backspace to delete both units.

6. CRASH!!

Bug report sent via email - [ Steve, sorry it sent 3 times - didn't mean to spam you, I didn't realize it did this - I was just making sure I could reproduce this bug, and verifying these steps]

Game save attached.

Experimenting with this further, I noticed that the crash was occurring when I was selecting both the Norwegian SCS units via the Naval Review Details form, and then hitting the backspace key to destroy them. If instead, I select them individually, either from the hex directly, or from the pick list, the game automatically deletes them, and the game continues normally without crashing.

Bug confirmed. If you select both naval units, the crash occurs. If you select them one at a time, there's no bug.
