TWD - Unable To Move In Episode 1 Epilogue
 

Having had a glitch-free experience to this point, I find myself in a position where, following the conversations with Glenn and Ken, it reverts me back to the starting position, where I'm unable to move in order to complete the level.

Reloaded the save four times, rewinded a few chapters, no dice, always the same game-breaking occurrence at this point of the game.

Ridiculous to spend £15 on something and have it break after just an hour of play. A solution would be much appreciated, as skipping straight to Chapter 2 means missing out on the related trophy.
