Arc Hunter Warmind Cell Modular Lightning seems to cause instance crash or failure
I am playing a Hunter Arcstrider Way of the Warrior using seasonal mods:
Head: Chosen of the Warmind
Arms: Hammer of the Warmind
Chest: Tyrant's Surge
Feet: nothing special (Frostees)
Cloak: Modular Lightning
Twice now, when I have triggered Modular Lightning's chain arc damage in combination with Chosen of the Warmind's concussive blast while near an enemy spawn, I have seen the enemies inside the spawn or at the edge of where they appear initially showing up already taking arc damage and dying. This happens for a few seconds in a cascade of damage seemingly hurting enemies as or before they actually appear. Then a few seconds later, I get dropped from the instance with a generic error message. My fireteam members don't.
Once was at the EDZ Seraph tower with enemies dropping from a Fallen ship and the arc damage was visible as enemies appeared out of the round drop holes. The second time was with hive (mostly thralls) inside the Witches Ritual public event on the Rig on Titan up near the barrier.
Seems semi-repeatable.
