Hi, my RW says it doesn’t save changes (minor changes). What can I do ?
Did you already try saving your project with “Save as…” under a different name?
Thanks for your answer. I wanted to try that this morning, but, in fact, after my computer restarted, the bug has disappeared and RW save my chages again… 
FYI this also happens to me sometimes. Save as doesn’t work either. Happened yesterday. Finally was able to save and I don’t know why.
