XF 1.5 Forum shows the same date throughout entire frontpage

[club98]

Hello! May be somebody could help here:
Forum shows the same date throughout entire frontpage
I find out, that it is mistake in template Node_forum_level_2
the code:

 <span class="lastThreadMeta">
                    <span class="lastThreadUser"><xen:if is="{xen:helper isIgnored, $forum.last_post_user_id}">{xen:phrase ignored_member}<xen:else /><xen:username user="$forum.lastPost" /></xen:if>,</span>
                    <xen:datetime time="$forum.lastPost.date, 'd.m.Y'" class="muted lastThreadDate" data-latest="{xen:phrase latest}: " />
                </span>

So, as I assume, $forum.lastPost.date this parameter returns the latest post date through entire forum, but I need it only from this spesific subforum.
