As you may have noticed, there is a distinct absence of mods on the database.
I don't know the exact cause at the moment, but rest assured that the mods are not lost. There appears to be a database problem, but the content is OK.
This post will be updated as I know what's happening.
Administrator (INtense!) Note: Greg, just investigated this and the mod table was struggling processing stuff... (with 600,000 records things like this happens) but it has now been repaired..
