Strange thing. After I upgrade my DB and remove info about migration:

I create next migration with some changes. (it has now matter which. Just add some field to any table for example). While doing that I get the warning:

Overwriting existing upgrade-diff file - /home/kes/work/projects/tucha/monkeyman/share/migrations/PostgreSQL/upgrade/129-130/001-auto.sql at /home/kes/work/projects/tucha/monkeyman/local/lib/perl5/DBIx/Class/DeploymentHandler/WithReasonableDefaults.pm line 18.

SQL::Translator::Diff::schema_diff(): Renamed column can't find old column "order.last_bill_date" for renamed column

The warning come when deploy/129/001-auto.yml file is accessed/analized

I do not understand why it says that last_bill_date can not be found. It is obvious why: for scheme 129 the column last_bill_date was renamed to billed_to.

last_bill_date was at 128 scheme and there is no such field at 129 scheme. DBIx::Class::Migration should not try to find last_bill_date for 129, to my mind
