Hmmm… There ‘might’ be something else at play here, I had a weird issue myself late last week that I am still trying to determine what it actually is with the WordPress WXR Export/Import, I have a sneaking suspicion it has something to do with the imported ID’s not matching the post_parent ID.

I’ll dig around more on this later in the week when I finish up the bbPress 2.x importer (it’s 75% complete), so watch out for any patches added to this bbPress ticket #2605
