On the map after I defeated Arctura, my computer crashed (blue screen, forced reset) This occured immediately after I saw the Phantom Slasher images and Rhue says "No way!" I was able to replicate this bug twice.
When glancing at the coding, I couldn't see anything wrong, I fixed it by having the game skip the map and move on to the scene at Estrana.
EDIT: It 'blue screens' in the Pits ending as well, shortly after Rhue finishes talking to Gaius and Slade. I will check Lexus' ending later.
