As reported here: https://forums.daybreakgames.com/eq/index.php?threads/aten-ha-ra-raid-crashes.281081/ it was supposedly fixed and we have not had a problem until tonight. I cannot post on that thread as it is locked (Resolved). Bertox server. We failed once on Doomshade. When we returned to try again, people started crashing, mostly during the buffing before we began. Next time we will drop the expedition and get a new one whenever we fail and it resets, but we didn't because it was supposedly fixed. Thank you.
Confirmed the same situation on E Marr server. Running raids and on rebuff we had multiple people crash. We couldn't specify which buff it was that was making people crash as it was happening randomly. This was on Sontalak Raid. Wiped and delayed due to multiple people crashing.
