Classic Twisting Corridors-Death upon arrival...?

Group of friends and I started our first level of TC which ran fairly smoothly until around layer 9...Upon arriving into the 10th level, we all just, well, died. For no reason. No debuffs, nothing appears in combat log, no effects, just death. Fine, we muscled through and happened again on level 11. By this time, of course we were out of deaths and had to retreat.. this experience has made me more than nervous to run it again, due to not having alot of game time....Has anyone else experienced death upon arrival? via /r/wow https://ift.tt/3fEgkVq
