Seneschal disappears on couch co-op [ps5]

When i play couch co-op my Seneschal constantly disappears. I cannot tell if it is glitching out or if it is being left behind, but it happens all the time. 5-10 times per nightmare dungeon.
This never occurs when i am playing single player.
I am always Player1.

It prevents us from bring able to advance through the Nightmare Dungeon levels. Ill say out loud “my construct is gone again” and 5 seconds later i am dead.
Season 3 is all about building your character around the benefits the Seneschal provides and its a major handicap when it bugs out.

Thank you for your time.
