I've just been farming totems and player xp by auto-running the Light element Boss Dungeon.
My team is Kobal/Therand/Dagrund/Emily. Seems like every 3 to 4 runs, when I hit the button on the team select screen to start the dungeon, I get an "Error: Bad Gateway" message and the game crashes. This is just particularly weird because it seems to happen almost on a pattern. Every 3 or 4 runs, to be precise. It's not too big of a thing, but it is annoying. And I found it weird that it keeps happening on an interval.
