I am editing the project on a gateway. I started by copying the running project. I then fixed the problems that caused (duplicated transaction groups,etc) then ran a backup of the gateway. I then modified the new project. This morning the power was cycled on the gateway and a vision client and the new project on the gateway is now gone. I have a backup that should recover most of the modifications, but now I am trying to figure out what happened to the project.
Problem solved. It was not Ignition. It was a problem with disk caching on the Gateway computer
