When i type anything in orename field, and exit from progression menu and open it again, orename field changes to "IGNORE" How i can use OreDict?

Saving in the 1.7 was very buggy, make sure to edit in single player,
if it still refuses you can always edit the json. Saving has been improved for future versions. I'm done with the 1.7 version which was an experimental mod for me anyway.
