I have noticed that when you distribute a package to a DP it shows up fairly quickly in the console as 100% "successful" (green). If I then start the execution of a task sequence it will fail due to a package that's not available on the DP..
If I go back to the console, after a while the package status turns over to "in progress" (yellow) instead and won't turn back to "successful" (green) again for 5-10 min..
Cannot find anything obvous in the logs about SCCM resending the package..
Hope this is a RC bug..
