Tried to play the Weekly Event (the darkness/extra specials/torch variant) a few times and got a series of crashes. One of our clients crashed during one of the levels, and then later on was unable to join and would crash every time while trying to join the in-progress weekly event level (Hunger in the Dark).
In our furthest run in Athel Yenlui, the host crashed after we got to the first ruined temple area with the three buttons.
