Multi-DB 3.0.5, WP 3.1
On at least two separate custom themes, when I upgrade or downgrade Multi-DB, all text widgets are lost. Other widget types are preserved (as far as I can tell), but all text widgets disappear. This is repeatable (but a major PITA to correct). Any ideas how I can prevent this and the best way to recover the data from my backups? In multiple tests, reverting portions (widget_% and %sidebar% keys), or even the entire options table for the blog will not fix it.
Currently, I'm reviewing the google cache for each blog and manually recreating it from the source. This is insane.
