I did get it to work eventually, I realised I was jumping a bit too early, so I would just end up back at the beginning every time.

So I found out about this glitch just today. I saw that most of the latest console runs are from around end of February, and when trying it, I'll hit the loading screen where I should go into the lab, but instead I just get put back in the room with the initial window I climb into.

So am I doing something wrong, or has it possibly been patched?

If it makes any difference, I'm on Xbox One

Yeah, we have a Twitch app, so without a CC, there's no way for me to put a timer into the video itself, just a link to the splits really.

I would've submitted a timer with mine, but I stream through the Xbox One Twitch app, so can't include that stuff. Would just a livesplit timer be fine if I use one in another run anytime?
