I finished playing Episode 4 and after the credits it took me to the main menu like it normally does. I quit for the day and then the next day tried to start Episode 5. My save file says Episode 4 Chapter 5: Medicine if I try to hit Play it says I need to GET Episode 4. I checked my downloads list and it says all the episodes are downloaded except Episode 4. I tried to start Episode 5 anyway and it asks me if I want it to automatically make decisions for Episode 4. I started to redownload Episode 4 and then cancelled it before it started and now Episode 4 is giving me the option to play it again.
I'm going to try and make my decisions again but this should be looked into for future episodes.
I know this has nothing to do with it but the only thing that changed between Episode 4 yesterday and Episode 5 today is that I also bought The Walking Dead for my PC. I know that at the beginning of both the PC and iOS app says "Connecting..." but I don't think they are linking to each other.
