sometimes, after entering a new level of the 'works, the graphics don't load.
The game is still running, I can swing my sword and hear it, but the screen is completely black.

There are a few elements still visible - the health bar and party health bar, but everything else is black. even if I hit 'esc' to bring up the options menu, I can hover over it and see my cursor change, but I can't see the menu.
