Oh Dear, we appear to be playing in the wrong stadium...

I am playing as Corinthians in Brazil. We got a new stadium, Estadio do Corinthians, on 1/1/2013. However, when playing local rivals Santos, for some reason we played in the old stadium, Pacaeumbu (or something, I'm not Brazilian, if you couldn't tell), which was 6,000 seats smaller.

In Brazil, sometimes local rivals play each other in different stadiums (e.g. derbies in Rio de Janiero are played in the Maracana), but that doesn't explain playing into the old, smaller stadium.

I'll post this in the bug forum as well, unless I'm missing something...
