Freezing and Crashing

[Aar7]

The program freezes and crashes for unknown reasons.

The first time it froze was when renaming a newly created system. I chose a name that, already existed and, upon renaming, the program froze and crashed.
The second time it crashed was when rearranging planets (I just clicked and dragged a random planet) in one of my systems.

Looks like I'll have to use the old ways until this is sorted.

P.S. How do I add labels to this issue?

I have some WIP branches (from when I had a lot more free time) that began dealing with all the fallout associated with name-based keying of the map data, when it comes to multiple entities with the same name. To avoid this crash until a fix can be created (no ETA), don't use the same name for systems or planets.

Not sure on the reason for the second crash though.
