The language reportcard relies on data gathering from the user properties table. If not gathered daily, this data is effectively "erased" because it's just a state storage and doesn't show changes over time. The recent changes to the query and datafile have created a join over more than 61 tables, which exceeds the MariaDB limit. So I have to split up the query, data files, and graphs, as well as update the manual cron job that gathers the data. Otherwise data would be lost. Using priority "Unbreak Now" to signify this urgency.
