T16 Elder Guardian map deleted the boss and did not spawn an Elder portal.

Reference number: 4073755625

Was running an Elder Guardian map on the Shrine layout, got to the boss room, and noticed that the boss didn't immediately get yoinked by Elder like they normally do. Fully cleared the boss room, there is no Elder portal to fight the Elder Guardian, there is no map boss, and the map is not listed as complete.

Have never seen this happen before, maybe this is an issue specifically with the Shrine layout? I'm not really sure.

EDIT: There was a damageable Elder portal on the center right side of the boss arena that I killed, but no Elder portal that I can interact with at all.

EDIT 2: Apparently the boss started outside the boss arena, then went INTO the boss arena, then got yoinked by Elder and caused the Elder portal to spawn OUTSIDE the boss arena. Maybe should be fixed so that the portal spawns inside the boss arena for consistency.
