I'm Getting an odd glitch, when I try to open chests on chapter six, after a certain point Shad is unable to open them. I tried trading the lockpicks to someone else, then trading them back, but it didn't fix the problem. Later, It didn't work on the doors either. I was starting to get quite confused. Also, related to chapter 6, I can't find Sue, or whatever other name she has. I unlocked all the doors and she isn't there. Is she down the stairs in the room she's normally in during the regular game?
