OS X crash log?

[sgqwonkian]

Open up Terminal (it's in the Utilities folder).

Once it's open, at the prompt, type:

cd /Applications/Weird\ Worlds/Weird\ Worlds.app/Contents/MacOS
./ww -verbose

When you hit return, it will open up Weird Worlds while keeping the Terminal window up in the background. After the game crashes, the Terminal window will be full of text, which, amongst all the notes about fleets and worlds generated, should hopefully include some clues as to why the game crashed. Sometimes the error messages make perfect sense, but more often they're a little obtuse.

You'll probably want to run it once without any mods (and thus without crashing) for a full game, so you can look over the data it put in the Terminal window. Then you can use that as a "control" or baseline to compare to the output when a mod crashes.
