Unable to attack Head Hobgoblins in Pantay Swamp?

  I went to artefact-hunting in Pantay Swamp and for some reason, I could not attack the Head Hobgoblins that came with the chests there.
  
  

  
  
  • I am able to attack all other mobs around the Swamp/mobs other than the Head Hobgoblins that spawn with the chests.
    
  • I am sure it is not position lag. They could attack me, but I couldn't retaliate at all. I tried to retaliate, but even though the target circle registered and I was "supposed to be attacking it", I was unable to.
    
  • Using AoE pets did not hit them at all.
    
  • I am not modding either.
    

  
  
  Is it just me? I don't know how to fix it if so...It has never happened before. Any help would be appreciated, thanks!
