You can put hours of work into customizations. Then, you
make a small tweak - say, add a button to an activity
- or Harmony makes a software update - and POOF!
On a One I've set up 17 Activities using 11 Devices and have regularly made adjustments, a whole of lot of them, and have never had that experience - the changes downloaded to the remote without a failure.
Suggestions for your very different experience: a faulty remote, or a faulty internet connection.
