New Family v0.4.7 Release - Tier1

Hey everyone.
Version 4.7 is out.

This is a small update. I was only able to add the extended massage level scene for Lena this time.

Originally, my plan was to write a devlog around this time, then add Yuno and Miho scenes on top of the current progress, and release everything next month as version 5.5.
But while fixing the massage system code, new bugs kept appearing.
Some old save files also stopped working, and a few other issues came up.

The good part is that I fixed almost all the bugs I found.
The save file compatibility issue should also be solved now.
All my test saves work fine.
However, since I patched the code on top of the old structure instead of rewriting it cleanly, the system still feels a little unstable.

So I decided to release this version now.
If your old saves do not work, please tell me as soon as possible so I can fix the problem quickly.

Thank you for your patience and support.
