column.visible does not appear work with sateSave

pwd

I have set the option stateSave to true and for some (one in example) set the columns.visible to false. unless I comment out
the stateSave option the column is still visible. I am using the buttons extension to allow the user to control which columns are
seen. The data is loaded via ajax one time.

If I allow responsive: true everything works (at least it looks like it does) but if I allow the stateSave the "base" column still
shows up (it can be turned off with the 'colvis' button but the colvisRestore puts the base back on).

This is the top of my datatables.js file:
Note DataTables 1.10.12

Did you enable the state saving before you hide the column? If so, it will have state saved the fact that it was visible!
