We are experiencing some inconsistent loading of CSS on an Odoo database hosted on Odoo.sh. When sending invoices in bulk the CSS randomly fails to load for a few invoices and then loads fine again after a while. During a bulk process of invoices I tracked down that the URL of the web.report_assets_common.min.css switch on 12:05:22 resulting in a 404 when requesting the old URL. It seems that Odoo keeps requesting the old URL while generating the invoice PDFs but after a while yet another URL is used and the CSS is loaded again in the PDF report.
