Drush 8.0.3 cannot update custom module I have a few custom modules that updates are being served from a D6 site with the Feature Server (fserver) module. Before updating drush, the drush up command on a site would see there were updates for them just fine. Now I get:
$ drush up uni_blocks_antares

No code updates available.                                           [ok]

But when I check that module's info it exists.
$ drush pmi uni_blocks_antares

I found that updating through the web interface of the site will see an update(version 2.8) and update the module.
How do I get drush up to work again for it?
What I ended up doing was updating drush to 8.0.5 and that solved it.
