I'm not sure what to do after the sequence in the mason library with the falling chandelier. I've looked at some walkthoughs and from what I can tell, the second scarecrow scene is supposed to start when walking down the hall in the next room. This doesn't happen. I've wandered all the way outdoors before realizing that I didn't have an objective. Am I missing something or has my game just died? And if this is a known glitch, is there anyway to fix it? Because as much as I loved playing  so far, I really don't want to have to do it all over, especially since I've been on hard. Any information would be great. Thanks.

Just to clarify, I know that the scarecrow sequence is meant to look glitchy. That's not the problem though. The hall that you walk down forever is just the normal hall you walked in through. I can get to any other part of the map even though that scarecrow part is supposed to trigger in that room.
 
I really like this game and want to beat it, but starting over after putting time in on hard is just heartbreaking. If there is no way to recover my progress I might just return it. Two other games lost progress on me this week, and a third would be too much. Investing time and effort into something and having it fall apart for no good reason really sucks.

you sound screwed ! 
 
if the hall doesnt get all trippy which leads to the scarecrow sequence, then yes my good man you're unable to progress.   How to initiate the hall trippiness, is something i dont know 
 
good luck !

I've no idea how to fix this but I'm guessing you're playing the 360 version?

Yeah, 360. Is this something that has happened to others, or is the 360 just more glitch prone in general?

I've played through the entire game almost twice (progressing through hard atm) on my 360 and everything has run smooth for me.
