Redeploy not working in Rancher 1.3

Not sure if it's an API updated, but I'm getting the following output on a redeploy command.

time="2017-01-10T21:57:24Z" level=fatal msg="Failed to read project: yaml: unmarshal errors:\n  line 1: cannot unmarshal !!str `2` into map[string]interface {}"

I did an in-service upgrade to the Cowbell service itself, thinking it might have stale API keys, but it's still not working. Here's the full container log:

The {docker|rancher}-compose.yml files that live in /tmp/compose-#### are docker-compose v2. Perhaps that's the issue?
