it's a bug that happens to like half of people
It gave me the "Escape" ending the first time but then got the bad ending bug every time afterward.
i think you can only get the escape ending the first time if you go for the revenge ending it bugs out and you will have to redo the first fight again
oh i see, any way to reliantly bypass it? Or do I just keep trying and pray it works out?
I think you just gotta pray it works
or wait until the patch that fixes it
i managed to get it by just sprinting for the door without saving after beating toriel, might have something to do with saving in general
wish you good luck on the fixes <3
