Hi hymeji, thank you so much for recording that video, it really helped me diagnose the issue!! I've tried a bunch of fixes but in the end I've just uploaded a new patch that gets rid of the bubble animation for all the reflections and replaces it with just a sound effect as it seems like the 'play movie' function inside RPGmaker seems to not like playing small animations frequently like what was being done with the bubble animation in-game
I really appreciate you taking the time to help me with this, I want everyone to be able to play the game no matter what computer they have so I think removing the animation is worth it as long as everyone can enjoy the game without freezing
