Death from ceiling tiles

Not sure where to put this. It doesn't seem like a bug, but it sure seems out of line with the rest of the game.

Playing the SSF 2-week, I was just doing a level 4 Haku mission in Haunted Temple in Cruel Act 3. After killing the Rua totem and grabbing the spirit, I navigated my way back to the final room with the exit when a bunch shit started to fall from the ceiling. One hit cleared my ES and stunned me. The second cleared my life pool. And that was that.

On the one hand, I feel like a wuss for posting this. On the other, this is some ol' bullshit. I mean, I got chain-stunned/-frozen to death a dozen times from Invasion bosses the past two 2-weeks and never felt the need to complain about it. But... Unavoidable environmental effects two-shotting me?! Was there something I was supposed to do?

Sooo... I guess that's my feedback. I don't like dying to ceiling tiles. :/

How long did you spend in there? I haven't seen this in a long time but dungeon's used to collapse if you took too long.
