As explained on our forums, we had to do this as one of the databases became corrupt after all the updates. I could go through a whole bunch of databases and find the corrupt file, but I really don't have 5 hours to spare to do that atm.
The updates were supposed to take around 30 minutes and that alone ended up taking around 6 hours of my time. So I took the easy route. As Luthier would say, these stats are just a "placeholder" for what we have in the works anyhow
