Im inside Yahhoy Fort West and i was fighting a Giant Rat Recruit when i got Hammer Assaulted by it then it just stopped doing anything and did not continue attacking. Ontop of that i am stuck in stun even after the stun timer finished. One last note is when i got Hammer Assaulted it showed me receiving a "buff" and not that i got attacked or had a status effect applied to me. Here you can see me still stunned even after the stun timer finished and the monster not aggro'd on me anymore.
I want to also mention that since i was stuck in stun i had to relog and when i logged back in i was in another part of this area.
