Hey,

For some reason, when I create a 6th forum under a category, it’s not shown. Posts from the forum still show up in latest posts widget and so on, but not in index anywhere.

It’s likely your theme that is screwing things up.

Temporarily switch you theme to TwentyTen/Eleven and see if that fixes it. If it does then your theme is doing some odd stuff behind the scenes that is screwing with bbPress.

Seems so, I’m using 2.1 beta version, which, as far as I understand, don’t need a child theme. Is there anything specific I should look for?

Correct, with bbPress 2.1 the “Theme compat” bbPress theme will work for most people out of the box.

The problem is that some WordPress themes do weird things – such as modify the loop and/or query (things that are not normal) – and this causes bbPress to break.
