Read posts reappearing 'unread'

[Scotty]

Since yesterday almost every post in some sections is now marked as 'un-read' - some posts are several years old.

In all cases it is showing the last poster as the new mod 'matthewn1983', even though he may not have posted in the thread.

Did somebody break something

I did move some old posts into new sections, however it shouldn't have my name next to it.
