I know . The problem is that the index in database results do not match the comment id.
I was sending for quip_start value the [[+id]] of the comment in the chunk for latest comments
<li class="[[+cls]][[+alt]]">
<a href="[[+url:replace=`#[[+idprefix]][[+id]]==?quip_start=[[+id]]&quip_limit=5#[[+idprefix]][[+id]]`]]">[[+body:ellipsis=`[[+bodyLimit]]`]]</a>
<br /><span class="author">por [[+name]]</span>
<br /><span class="miniText">hace [[+createdon:ago]]</span>
<br />
</li>
So, comment id 68 don´t work if there is only 25 records (due to deleted comments). So quip take default value 0.
I'll try to solve with a modifier and QuipCount.
Sorry
