Grimm Eclipse Mountain Glenn crash investigation

Every single time in the third stage, when reaching the cutscene at the entrance to the city, the video freezes, followed shortly by a game crash. I've confirmed its not just me (I've watched players reach the same point and disconnect from the party), and I've narrowed it down to an access violation in GPU memory (graphics card crashes when the visuals freeze and Unity throws an exception listing register 0x0000009C). I've also found other Unity games commonly experience this exception. I'm betting it's an issue of incompatibility between the code and specific graphics cards.

If you've also experienced this issue, please post your OS, graphics card, and graphics driver and version to help the game team solve this issue.

OS: Win 8.1, card: Intel HD graphics 4600, driver: Intel graphics driver v10.18.10.3308
