0.7.1 - Proton: Empty Loot menu screen with arrow key press

I defeated a nether boss and the loot screen popped up. I think I pressed the down key sometime before the 1st page was shown.
I got an empty loot page (probably a nonexistent page or something), I pressed Q for fear of the game crashing.
If it matters, I had the strict loot filter on as well.
