I haven't played much and i like to keep my memory fresh to remember things clearly so i'll be updating this post if i find new bugs.
As for now, there is a bug with being able to choose Val as your companion during her stay at the med room, it requires you to just not reset the choosed ally, because it tryes to fill it (ally slot was yellow and clicking it brought Val). Most likely i was able to after i left the menu with Val chosen in the party tab (well, thats my only clue anyway)
Thats how it looks in battle tho



Sometimes THE SQUARE tryes to kill my team. No idea why or how it just appears on some attacks and slides over the screen, animation or effects bug i'd assume?
