I created a migration with a query that seems to have broken my migration. I added two groupBy on a query, instead of two orderBys. As a result, running drush mi MyMigration got stuck in what appeared to be an endless loop.
I CTRL-C'd the process and then ran a drush mst --all, but now the status is reporting as "Stopping" in the UI, and the drush ms command does not return.
I tried stoping and restarting MAMP, but to no effect.
Is there someway to force my migration to get unstuck?
