You run ESO and right before the portal spawns the host drops forcing a migration (seeing more and more of this every day) that does one of two things.
1. You are forced to the next level even when you did not enter the portal.
2. Or you are stuck in the same level without any critters and the timer set back to max time.
As much as I am seeing this now it seems more like griefing instead of actual crashing.
