Deployment from command line returns failure, but did install

I have deployments that use the command line tool through Octopus Deploy. Octopus Deploy is saying the deployment step with Polydeploy failed because polydeploy returns a failure. However when I go to my DNN site all the module versions updated, the database updated, and I all the views update. It appears that the deployment was really successful. How can I best trouble shoot this issue and see if it is something on my end or if there is a possible bug in the command line tool? When I look through the PolyDeploy logs I dont see any failures, but maybe I am looking in the wrong place.
