I was playing the game again so I could fill out the rest of the wiki, but I decided to reload previous chapters in order to fulfill side missions for infinite ammo, car parts, etc. Anyway, I just wanted to let everyone know that once you get the key from Olivia Cormack to open the back yard of the A&G Diner, DO NOT RELOAD AND COMPLETE A PREVIOUS CHAPTER! Doing so will overwrite your inventory and get rid of the key needed to progress the plot!

I can't say I’m surprised that there's one in there. 
I just hope Brian and Jenny see this otherwise we may have a premature conclusion to the ER.    

Brian and Jenny? What? :p
 
Anyway, I doubt this'll happen to the ER, because they are certainly not planning on playing this game for even a second longer than they have to. Replaying chapters is not part of the deal, especially not for Brad.

Just got hit by the Chapter 9 key glitch in my first play through. What a shame. I was enjoying how ridiculous this game is. I don't think I can stomach starting over from the beginning again.

I had this happen to me and was absolutely LUCKY I happen to backup my save on MU just prior to trying to reload a chapter and do the side missions. It took me awhile to figure what I hell I did wrong. This was the first glitch I found with respect to replaying chapters and haven't had any other issues YET. :)

I really hope they see this. We don't want the ER to end because of this glitch.

There's no way they will reload chapters. There is no danger of this happening in the ER.

You know, I find it funny how most of you assumed I posted this for the ER. Nay, it was for if you were playing the game on your own time.
