Every. Single. Time. I finish the my game of Phoenix Point and it loads after the Synedrion ending cutscene. As soon as it finishes loading it crashes. I've reloaded the same save 3 times and it's done it each time. The first time the cut scene was skipping, freezing and the captions were behind the audio+video then crashed.
Sorry to hear of this crashing @Aeruthus, especially at such an important part of the game. I think it has to do with the developers rather than Stadia. I would suggest writing a support ticket to SnapShot Games to see if it's something they are aware of or have any troubleshooting tips.
Im experiencing the same error. It occurs at cutscenes whether its the 1st or 3rd map. Extreme aggro.
