So, I installed the latest update, and now I'm getting a few new errors.
If I try to click on the Network Inventory interface, I get the message "Item is not a blueprint / Refined Network Storage: failed to open gui"
But every second or so I get a new message in a continuous stream of errors:
"'stack: table expected, got nil / Refined Network Storage: An Error occured while updating an entity: RNS NetworkController"
If I picked up a controller from one of my networks and place it down again, I still can't access through the interface.
Will be happy to provide any additional info, just let me know how :)
