I'm sorry to hear about these problems :/ I will check more carefully the Elise / Felicia line and try to get a fix out along with next patch (end of March/early April).
Regarding the save data issues, some key changes have been made in 0.4.05, which include a patch to the engine itself as there are some underlying issues beyond my control. Did you experience the save issues on a fresh run started on 0.4.05, or did you load an older save?
