So I've noticed this game has a pretty significant issue and I didn't see anyone else even mention it. Although a few have most definitely experienced it without realizing the cause.
Holding 'Shift' is how you switch between running and walking. It is also the key you press to toggle the display of text windows. All text windows. Cutscenes, H scenes, idle villager chat, battle menus... All Text Windows! The issues arise because absolutely nothing is stopping you from disabling text windows even when there is no text on screen!
What this means is, if you hold shift to position yourself for any reason and then get into a battle or simply talk to someone, the game will completely lock up until you press shift again and at no point is any of this ever explained!
How does shit like this even happen?!
