Bug Report ID: #2273665650. Vastweld, the Colossal Guardian.

Fight initially started fine, I was hitting the boss and he was able to damage me. Then at about 85% boss health, my minions and my spells could not damage the boss although he continued to fight and do damage. I logged out to Character Select screen, relogged back into game and re-entered the boss arena. At this point, the boss was still damaged and not reset back to full health. This time around, I still cannot damage the boss and he is not attacking me either.

Any news on this? Same issue happened to me as a Warrior during campaign once and now again in Forge map. I cant seem to reset the fight by any means and am just locked into the fight. Boss cannot be damaged anymore, but I still take damage from his hits.

Same here in a map. Also like 85% HP remaining on the boss and no more dmg possible.

same issue here today on my Warrior. Couldn't deal any damage past ~85% HP.
No skill worked. Looked like he could not be aimed, as he's not on the platform.
