Warning: Cannot use a scalar value as an array

I'm using custom tables, maybe that has something to do with it?

Anh, what data type should I be using for the custom table storage?

MB_Custom_Table_API::create( 'hcr_location_meta', array(
'hcr_location_type' => 'TEXT NOT NULL',
'hcr_location_address' => 'TEXT NOT NULL',
'hcr_location_map'   => '??????????',
) );

And yes it is happening on new posts and old. Only on pages that contain the metabox with geolocation however. I think it has something to do with the custom table storage. Let me test that theory.
