There's a glitch that fuses Operator & Drifter together in 1999 and.. oh dear god
Since Hollvania force-equips Drifter on you even if you still have Operator equipped outside of it (like in the Orbiter, you can see him in the mirror at the beginning), trying to edit your character can result in.. this monstrosity that Arthur needs to take out back and end it's suffering
Luckily (as funny as it would be) it's not permanent and goes right back to "normal" if you close the game or do a mission and come back. Just when you thought Drifter couldn't get uglier 😉
