yes i had to turn on no-clip just prior to sleeping in the bed if you enable no clip then move to the bed it wont allow you to sleep so stand in front of the bed where it should allow you to sleep then enable no-clip, then sleep when the scene is finished fly to a safe spot in the dream and then disable no-clip and viola youre ready to continue, but nonetheless im pretty confused on how this had gotten so broken in this version maybe the author had made the update and had no idea this would be an impact of the change and hadnt retested the game prior to release. All in all it would be something anyone could miss. would just have to move the spawn node up just a hair to prevent the MC from falling through the floor
The problem is that the textures are there which is why you see the floor, but he missed a small area when navmeshing it. Because of that, as soon as the short wake up video is over and control is back to the game, there is no floor there really, just the illusion of it, and you fall.
You are right though, it's an easy to make mistake, happens allot more than most people think. It is hard to believe it wasn't noticed on a final test playthrough before release though. And so close to the end, which means they probably rushed that update and didn't fully test it.
Still it will be an easy fix once they get to it, although I'm still kinda upset (yes I understand Patreon rules sucks) about all the cut content.
