ceylon.json/1.3.1from my cache and reopened your project, it was downloaded correctly (both .js and .src files)
.missingfiles should only be created when the Herd explicitly tells us that the file doesn't exist. So the same way we don't have a "redownload" option (because artifacts never change) there should theoretically also not be a need for a "retry missing files" option. If they appeared without reason then that is a bug.
