Act 2 first area boss gets frozen/stuck

The first boss of the first area in Act 2 is bugged. The leader of the Hyenas? Rathbreaker? (not sure if that is the correct name) gets stuck if leave the top of the area. He ran down a little to chase after me, but then went back up. Then when I went back up to defeat him after leaving the top area, he did not move. I attacked him but he was stuck. The boss took damage, but would recover all his health. The boss just stands there.


The issue is they give you the space to run from the area which makes sense since it is not a closed off area. You have to fight the boss at the top of the area and cannot move too down too much, or the boss fight will be bugged. Please fix.
