Their has also been some issue with discrepancies in different routes, which over the past month, we have fixed and is part of this next update.
The first route written is the uncle/aunt route, and the other routes were branched off that. and if I remember correctly, I think it was the cousin route that had a corruption stats glitch that caused it to fail on a few things.
One of the major changes in this next update is we completely separated the routes and script files into self contained paths where it only contains story for that route. The original files still exist so saves work, but if you start new, or load a save from day 2 and then go into day 3, you will be in the new diverged scripts.
This does require us to write each day 6 times, but it fixes these issues and allows for greater differences in the routes. Taking day 4 for example, Uncle/Aunt routes have a pretty awesome and unique experience with Alex, and the cousin route gets one with Kayla, and the family friend route, gets something completely unique with Ava.
