Topic count won´t update after moving topics to a different category.

Hello,

I suspect there may be a  bug in the topic counting function in the Categories page. I have recently introduced a new category (Archives) to my forum (biosemiotics.lefora.com) and moved some topics from elsewhere to this category. However, I just noticed that they are still being counted in the old category in the Topic and Post counts in the Categories page, Thus, these topics and posts are being counted twice - both in the original and in the new category.

However,  post count in Community info works fine (resulting in a mismatch between the total post counts reported in Categories and in Community info).

No real loss of functionality, but perhaps worth fixing?
