[Jaja..]

On my homepage i show the forums and behind that the last topics and last replies.

This shows the Avatar of the last person active on a topic (replies):

<?php bbp_author_link( array( 'post_id' => bbp_get_forum_last_active_id(), 'size' => 32, 'type' => 'avatar' ) ); ?>

Very cool, and works.

But now i would also like to call for the authors (topic starter) avatar of the last topic on a forum.

So i tried this but nope

<?php bbp_author_link( array( 'post_id' => bbp_get_forum_last_topic_author_id(), 'size' => 32, 'type' => 'avatar' ) ); ?>

It gives me random avatars from everybody.
