Just so you know what to look for:
1. when switching between the character menu quickly (especially when opening the character menu and summon menu in quick succession), arrow inputs to select menu options also causes your character to move
2. Sometimes when unsummoning monsters, the monster's stat card does not disappear and slides to the left of cecel's. The cards stack there with each monster having "null" hp and mp and remain there.
3. One particular door in the lighted window maze puts you in a soft lock scenario. Upon entering the door, you repeatedly enter the door you exit out of and then do the same in the other connected door. This puts you in state in an unmovable state in which you are unable to open any menu thus forcing you to force close the game.
Sorry, for the wall of text. Figure I should at least describe what I saw instead of saying "game broke" and making you search for some random UI glitches and a softlock I never described.
