Hi guys, I'm doing this post since a lot of people keep finding the 0.25 renpy bug. It seems that the bug "infected" the save, bringing the problem to 0.26. We found different solutions to solve the problem, and for each person it's different. So I will give you several options to solve it.
1° method
Try using rollbacks and ignore them when the problem appears, if you can get out, save and reload the save, if it works, you're fine
2° method
Try overwriting the renpy folder with the file uploaded in the post, since the bug comes from there, it might work
3° method
Use this healthy save and simply change the name.
In case you should have duplicate dialogs or problems with Tailé, use bugfix.
Sorry again for the inconvenience, I never expected that updating Renpy would cause all these problems.
