So i got a crash at the citadel of eternity, my team had made it all the way through the map and were standing in the portal and the finishing process + map stats reward was coming up when it just instantly CTD´s.
This has happened to me a few times and two others in the lobby (friendlisted and chatted afterwards) told me they have had the same problem.
Please find a fix ASAP! A CW expedition is really damn long so crashing at the final moment is tilting beyond words, especially when you had a good team whom you knew you were going to win the finale with : (
Also, the Nurgle miasma curse is awful and isnt fun to play at all, even less so 3 times in a row.
