Just bought Galactic Conquest. Worked well the first time, but messed up my first battle so I deleted and made a new one. After confirming the settings (rebels at Omega Centauri on easy) and selecting to begin it crashed.
Debug files, viewed minutes after this: (note position from the bottom, same the whole way through)
Edit: Worked fine again, but when I tried to create another campaign I got this line (thankfully only twice):
