Fixed a rare bug that caused Save OAR to fail because it thought it had timed-out 

The bug manifested as follows: a large world was saved. All the assets were found. But for some unknown reason, the timeout timer was restarted. So after 1 minute it closed the Archive Writer, because it didn't receive any more assets during that minute. That caused the OAR to become corrupted because ArchiveWriteRequestExecution.Save() was still running.
