This. And it does not just lock her in the attack stance, it makes all her skill unuseable.I just found a bug that makes Reniel utterly useless in combat. Make sure you swap her to attack stance on the day where you first got into Emerald Maze 2 because the day after you will be forced to visit the magical library.
After you found the book you have to fight a weak boss enemy that Reniel accidentally summoned. If she was in defense stance when you started the fight
(this will be your first fight of the day because you will be forced into this event after leaving the guild house)
there will be a weird animation and she switches to attack stance.
If this happens she will be locked into attack stance for the rest of the game
(this might fix itself if she leaves the party in future story segments)
and cant switch out of it anymore and is also not able to use her abilities.
if you have autosave from just before you entered the library at least, you can still switch her stance before you find the book.I have this as well. Any fix available or way to avoid it? I don´t have any save from before I went to sleep and the bug occured
