Had to redeploy, can git pull from command line, but quick deploy no longer works

I managed to introduce a laravel-breaking bug into our deployed code, and in trying to resolve it ended up freaking composer out and being unable to run migrations, much less anything else. So I went through attempting to revert everything I did in our master and then created a new production2 branch to deploy from off of that master (that's another cry-story in and of itself... I can't visualize git).

I deployed the production2 branch okay the first time, but now this branch will not fully update from Forge, nor in quick deploy.

From github.com:FaithInMotion/capstone
 * branch            production2 -> FETCH_HEAD
   7a2218d..a3b7c0d  production2 -> origin/production2

Composer could not find a composer.json file in /home/forge/default
To initialize a project, please create a composer.json file as described in the https://getcomposer.org/ "Getting Started" section

Our site works (I have corrected our meta to point to project/public like before), and I can SSH into the server and do a git pull origin production2 without an issue. I would really like for quick-deploy to work though, for the sake of the student who is using this branch for testing.

Ideas?
