Scheduled Tasks Deleted After CF 11 - Update 16

We installed the CF11 Update 16 today and it deleted all our scheduled tasks.  Unfortunately, we didn't notice until we installed on 3 other servers.  All tasks gone.

We tried to restore with a recent CF Archive from the Admin.  Did not restore tasks.

It looks like the system did create a backup of the old tasks file: neo-chron.bak.

However, when we rename this back to neo-chron.xml and restart the server, CF replaces it with a blank file and makes a backup again.

Any help or ideas?  Looks like we need to crawl through the XML and re-enter tasks by hand?

Logs look to show Null Point Exception:

"Error","localhost-startStop-1","02/15/19","14:14:25",,""

java.lang.NullPointerException
