[ic] timed-build breaks more list - help needed

[DB]

I'm running 4.8.8 using a modified foundation and MySQL. I have about 
150,000 items in the catalog. Instead of the stock category list along 
the left side of the page, I have links to custom pages which contain 
searches.

When customers click these links, the search is performed as expected. 
But because the database is getting large, these searches are slowing 
things down. Since the same search is performed each time these links 
are clicked, the timed-build tag should really help reduce the server load.

On one of these custom pages, I put [timed-build auto=1 force=1 
minutes=0] at the top of the page and [/timed-build] at the bottom. As 
expected the page loaded much faster.. almost instantly. The only 
problem is that the more list no longer functions. When I click "Next" 
or any other link from the more list, I just get the first page again. 
There is a big performance incentive for me to fix this so any hints are 
welcomed. I tried moving the [timed-biuld] tage to various places on the 
custom page but unless I wrapped almost the entire page, things broke 
(raw ITL tags were shown on the page). Below is an example of one of 
these custom pages' CONTENT section. If I wrap this whole section with 
[timed-build...], I get the speedup but a broken more list.
