download ending early and not restarting from previous spot

Description

User experienced high rate of restarts, but each time had downloaded a significant portion of the file and then the download restarted from the beginning (because of md5 mismatch on the whole file).

We should check the logic to make sure there aren't unexpected ways the download seems to be completed but isn't; and if there is a possibility of restarting from the previous point.
