i haven't reproduced this issue, but it's been reported by multiple people on discord
after beating the boss in dodongo's cavern and entering the blue light, the game crashes
this isn't a problem for everyone, and from what i can tell there's no clear config/setting fix/workaround.
from what i've gathered it doesn't matter if fast text is enabled or disabled. i think it happens on both directx and opengl but i'm not sure.
update: someone on discord with the issue managed to get past it with directx + turning off fast text (after seeing it fail with directx + fast text on)
