Black Crow Map Boss Untargetable/Invulnerable

Was doing the fight in the second area, burst him down and then he went enraged and became invincible. couldn't target him anymore, so i am simply stuck in the fight. Tried to exit to character selection screen, but that didn't reset the boss. Closed the game, but also didn't work. Character was in limbo. Alive but only way out was to die

RIP EXP
