Quick announcement:

Hello everyone. 

First of all I would like to apologize to you for the bug where the girls would disappear when creating a new game in 2.9.

Secondly, that bug has been fixed (please let me know if it works for you).

Sadly, fixing this bug and maintaining your game progress has been impossible for me, so if you have created a new game with the release of 2.9, it will be necessary to download the new fixed version and start a new one.

Note: If you updated from an older version and used an old save, you should not be encountering this bug.

I will try to describe the bug: 

This bug occurs the moment you decide to save your game (either by auto save, manual save, or quick save), close the game and then open it again to realize that the girls no longer appear on the map, your relationship with them is back to level 1 and you haven't unlocked any h-scene (even when you already did).
