Are you using an old save? It may be the problem. If Iono is level 51+, it should be that. If you start a fresh new game and find yourself with the same bug, hit us up on our email, on a DM on Patreon or Discord and we'll try to help you.
the save is new. i actually had to restart my save just a few days ago due to a different bug that had a couple random character sprites pop up whenever you interact with a character or go into a an event scene
