When doing the "Sharpen Senses" spell in order to catch the butterflies, I cannot progress because the spell just makes my screen glitch with nothing but pink, purple, and various solid colors until the spell wears off. I've tried changing the graphical options but nothing seems to help.
EDIT: Seems reloading my save file fixed it. It would seem I had a negative HP or something as my HP bar said 0 despite being alive. Reloading to before this glitch happened fixed it.
