Beginning with this morning's patch, I have began having issues with the NPCs in delves hitting me so hard that I fly backwards for an inordinate distance and literally through the wall of the delve. Once there, I am dead even though I had full health at the time I was hit. I was NOT "one shotted". I just turned up dead.
I can resurrect and see the playing area of the delve clearly, but I can't get through the barrier and back into the delve. The only way to fix the problem is to port out and then re-enter the delve in the normal way.
