For those UBB.Sitemaps users, especially if you've upgraded to v7.6.x+; the New URL Structure in v7.6.0 utilizes the same code as the [7.5.8] Better URL Sanitization for SEO modification, which has been in the UBB.Sitemaps code since v0.9 (April 2nd, 2015).

Please be sure that you enable the v7.6.0 style URLs within the sitemap:
Code
$conf["version"] = 3; // UBB.threads Version, 0 = v7.0 - v7.2.2, 1 = v7.3 - v7.4.2, 2 = v7.5 Series, 3* = v7.6 Series

Please note that the URL structure of v7.5.8-v7.5.9 are not utilized in the UBB.Sitemaps script, as they allow invalid characters which can break search engine crawling; the official fix was to install the aforementioned modification.
