Have you run into issues where your OSD task sequence deployments are not immediately available to your clients? This appears to be a bug since upgrading to SCCM 2012 R2 SP1. Since the upgrade, when deploying OSD task sequences they do not become available to the client until the next day.
If you are experiencing the same issue there is an easy fix. You can simply set the deployment availability for the day prior. This works and my deployments are now available to the client right away.
