@Liam3851 thanks a lot for the bug report and the fix!
Looks perfect, and thanks for adding legacy data (we should probably also add some data for 2.0-2.2 ..).
Can you add a note in the doc/source/whatsnew/v2.3.1.rst file? Because we will want to backport this fix

Thanks very much for the review @jorisvandenbossche, I've added pickles for 2.0-2.2 as extra checks and a whatsnew entry. |
