This is most likely to happen when you are with large groups of people doing a lot of world hopping. It has randomly happened to a decent amount of us in our group. While the issue doesn't happen too frequently it does happen often enough to be once or twice a day. Few things we can confirm is the the only time any of us crash is when people start going into a portal and that it happens on the main and open beta builds. I do have the output log saved of the recent crash, and would be willing to provide more as it happens. Not sure the best way to share output logs through the Canny but will be more than willing to as instructed on how to do so.
