So, I'm attempting to run module updates to make everything up to date, and try to migrate a site with quite a few images loaded using the old-style media_field to the newest versions of the media modules, and I seem to have run into a frustrating issue related to file fields for alt_text. Whenever I run the database update script (using drush) I get an error:

Table field_revision_field_file_image_alt_text already exists.

I look back at the database, and this table does, indeed exist. So I remove it, and run the database update script again, and I continue to get the same error. I looked at the update script, and it seems to be checking to make sure fields don't already exist before creating them. Perhaps there is something about the way I configured the site that is causing this check to not work correctly? Could it be that I created multiple media_field fields?
