filter references unknown column "{col}"; the condition passes every row

What happened

A condition names a column that has no data handle - it is not a column of this grid, or it is not loaded. There is nothing to test, so the condition passes every row and the filter does not narrow anything.

The fix

Check the column id in the condition. A saved filter restored against a different column set is the usual cause.
