The filter on bbp_has_forum doesn't catch $args from original query

[matrixino]

When using this plugin in combination with an alternate forum display (for example showing first-level subforums on the home too) the output is just a repeated list of main forums. I add a citation from the mod's author topic on bbpress forums.

I checked the code of this plugin and it uses a filter on bbp_has_forums
that tries to catch the $args from the original query but they are not
transmitted through the filter in bbPress, so it uses the default ones and
doesn’t take care of the post_parent argument. You should try to contact
the author of the plugin, maybe he can alter the query without parsing all
args again. The Codex says it is possible with $query->set().

Thanks for letting me know. I'll start looking into this.
