XF 1.1 Cannot get user post count correct


Well-known member
I've just imported a vB forum which went OK, rebuilt all the stuff it suggested.

However I notice a user which had a manually edited post count in vB (I changed it in the Admin CP to read something silly like 3000000 posts) has also had that - wrong - post count imported too. I would have thought when everything was rebuilt all user posts counts would be reset to their actual number?

How can I do this? I've tried rebuild user caches and rebuild thread information (with rebuild post counters ticked) and the member profile still shows completely the wrong post count.
