Woo hoo, fixed the layout problem (the code I did yesterday was good, but after an earlier problem I'd forgotted to change one +1 to a +2, and with that simple change it now works perfectly). All the stats added since the relaunch of the site should now display a lot better and should look very similar to the way stats looked when added before the relaunch.
Also after a suggestion sent in, I've marked all the Crossover stats as Crossover in the Official tab. So anyone wishing to see only the crossovers from other games and settings can now select that in the menu's.
