Elder guardian stuck if frozen by delirium during transition

Elder guardians don't progress to the next stage if you kill them while frozen by the delirium effect doing some attack.

Yea can confirm this bug happens if you push the threshold of their HP during the delirium ghost effect so the elder trigger to teleport them doesn't happen.

Same here.

Can confirm, happened on Eradicator fight in Volcano T14

At 2/3 life, end of first phase, the Constrictor went full life and stand still on edge of the arena unaffected by any type of damages below 2/3 life not triggering phase 2. Tried to disconnect and went back in the arena, did nothing.
