In TW with jmmw omicron jv are immune to instant defeat. In my battle jocasta was the last character and Jabba used the rancor which instantly defeated her and the screen to submit or forfeit the battle immediately came up. Jocasta never got into damage immunity to take a bonus turn and use her it's up to you now ability.
Is this the correct outcome? I don't think so since she shouldn't have even been defeated due to the omicron.
