Map Editor crash

Issue description

I'm not sure what happened but the game just ate my custom map file.

The game failed to initialize. Please file a bug report if this issue persists.

Reproduction steps

No clue how to reproduce it. I was using the editor, that's it. Something weird happened where all of the map polygon markers disappeared, and then I tried to save and load but the file is unloadable.

Game version and build number

v0.7.6a b466

Operating system

Windows

Would you still have the unloadable file for us to inspect?

Would you still have the unloadable file for us to inspect?

Sadly, no. The save was corrupted so I just deleted it and then posted the bug report, not realizing it could have been useful. Apologies.

Sadly, no. Since the file was corrupted, I ragequit and rage-deleted the file. I only realized it could be useful when you mentioned it.
