Did the Tag system change recently? It no longer goes beyond two pages worth of results, and as far as results go, searches are only showing two pages before the "see older" option is prompted.
Previously, tags listed up to 4 pages with a "see older" once you reach the last page, and searches did this same thing with 10 pages.
Tags only listing two pages with no option to see more makes them feel pointless as far as using them to find related threads goes. Is this a temporary setting or a permanent one? Searches, while slower, still have the "see older" option, so those are still doable if you have time (and Titles Only is as good as always).
