Hey there, yes that will happen if you leave for an expedition in the morning and don't make progress, since you're receiving a message for morning as well as noon. I'll include a bit of code soon which will prevent the game from printing repeat dialogue.
First playthrough, all locations accessible. Next playthrough it says that only the high school is accessible in the demo. Do I have the wrong version?
You can find all the locations, but you can not visit them all. That message is from when literally only the High School expedition worked, now you can access the College and Hospital as well, but the message still remains from the demo phase. I'll remove it soon, sorry for the confusion!
If you're playing the PC version I know anti-virus software can mess with UE4 games The Android version might need an update to work on certain cellphones, especially newer ones
