SPOILER Bug In Christmas Chaos??

There is a bug when you kill the relic thing and get the relic shard then talk to the guy and enter the portal, the problem is you die when you enter the portal because of fall damage and therefor can't proceed, as someone who has 2000 health and since this is a level 30 quest no level 30 can have that much health, even in full Legendary Armour. So this has to be a bug. This makes the quest uncompleteable, is this a bug or am I doing something wrong?

 

Died there the first time as well. Could get my way out by using rush as warrior just before I hit the water to neglect all fall damage. Teleport and escape for the mage and archer should work as well. As assassin you probably have a problem.

 

*levels up further then does the quest while they fix the problem*
