Stun Bug - AI "shutting off"

IDK if this is a known issue, but since today's patch, I've frequently had enemies not recover from stun. Afterward, they just stand there idle not attacking or reacting in any way. Presently I've had a Blood Chieftain gorilla mob standing idle in front of me for 5 minutes, as I type this. Just wanted to let you guys know. I appreciate all the great work you've done and the new art with the patch is outstanding!

Forgot the image, but I left him alone so he was still standing there, 15 minutes later.
