Just an small notification to inform that a hotfix for the January build was pushed out a couple of days ago that should fix Okisho's route. There was an error with the scene mapping that caused the route to not progress that should be fixed now. Redownload the build (it will say 01.16 in the file name to show it's updated from the original).

As a reminder, if you are on her route and have played WGB005, it is best to replay that scene (you can load it via the debug menu); this will ensure Aida's pregnancy scene triggers for the route. 

Speaking of Aida and fixes, in Aida's Gallery, for the life of me, I can't seem to unlock the second picture; it might be bugged. Additionally, there's a peculiar RP requirement after the Baseball event. When in bed, it states that it failed if you have more than 30 RP. However, given Aida's positive reaction, it seems that the requirement is incorrect.
