Critical Bug: During Titan Collossus boss fight on the platform, repeatedly fell off the edge

In the buried shrines waypoint boss fight, against the titan that climbs up. During the fight I teleported/fell/whatever off of the edge and was down there for 4 seconds not being able to see anything.

I was teleported back up, into a bunch of the flying adds that come into the fight, then again later in the boss fight I think I fell down 1-2 times more.

I'm playing Ranger, so luckily I have high evasion and survived, however that bug might cause someone to lose their Hardcore character.

Thank you and God Bless.
