+
+I've made a note of the error in [[<2023-03-27 Mon> Note: A Line of Lines has wrong dimensions][A Line of Lines has wrong dimensions]]. I made
+the correction directly in =data/artwork-2023-03-21.csv= because I am lazy. I
+didn't want to download the recently updated database, from the live site, and
+run the scripts to remove/clean it again. The change takes a few seconds (on my
+machine) but the downloading and cleaning of the database from the server; the
+exporting of the data to a CSV file and adding said CSV file is not.
