Bramble Valley Boss broken A.I.

The boss seemed to start a charge and put walls to the sides of use, I froze the boss and now it no longer has working A.I. Added images show Boss not reacting to me running circles around him, or being in melee range, or multiple minutes passing. Not sure if able to be replicated, is first time in this map.

Bug report reference number is 3,429,343,114








Edit

Boss also no longer takes damage.
