Just tested this out for the first time in a long while and it didn't seem to be working for me (I only have the first DLC, "The Signal"). The editor would load saves and seemingly edit values okay, but the game wouldn't recognise them at all. Opened the edited saves in Horizon and realised that the editor was adding the wrong device ID. Once I rehashed and resigned in Horizon, everything worked fine. Figured I would quickly mention this in case anyone ran into the same problem in the future.
