Updating theme to version 2.2 deleted all my sidebar widgets

If I had edited theme files this would make sense, but I didn’t.
The theme got rid of all my sidebar widgets, there are a lot of them and now I have to load a backup on a test server and copy them manually one by one, because if I load a backup and then update the theme they will dissapear again!

Been using this theme for more than a year, but after that I’ll be switching to something better.
