Some problems I found.
p.s. I posted this in the wrong forum the first time, sorry about that.
CRASH: ShipYard
Steps to reproduce:
1. Start a new game.
2. Click the ShipYard button at the bottom of the screen.
3. Highlight each of the existing ship designs and Obsolete them, until the list of ships is empty.
4. Click New.
5. Choose a Hull, click Save, click OK.
6. Crash!
Variation:
1. Start a new game.
2. Click the ShipYard button at the bottom of the screen.
3. Click New.
4. Choose a Hull, click Save, click OK.
5. Highlight each of the three built-in ship designs and Obsolete them, then obsolete the custom design created in step 4.
6. Notice the Upgrade button is still available even though there are no ships in the list.
7. Click Upgrade.
8. Crash!
UI Flaw: In the ShipYard there's no warning on the Obsolete button, it's very easy to obsolete one of the starting designs by mistake (which is how I found the above crash).
UI Flaw: The detailed description of Earth (double-click Earth, click Details) includes a "/n".
