Got it to work, thanks!

Yeah, the room with the nurse before you enter Wonder City. Once I go through that door nothing loads and it soft-locks. (After Ras's.) Nothing saves either

How come when I do the zip after Ras's fight to get back to the Wonder Tower area it doesn't save and it drops me into the void? Did I miss anything? On console.

Just wondering if Return To Arkham patches any glitches that are used in Any%.
