"The lock count should never be negative" after Clean Sum of Bests

[patrickmacarthur]

I am trying to use "Clean Sum of Bests" on a splits file for a run that recently had a re-route. Whether or not I accept the suggested cleanups, the splits file is not correctly updated and I see "The lock count should never be negative" when going back from the edit screen to the main screen.

The splits file does show in the UI as edited but afaik nothing has actually changed and the cleanups are not reflected in the Sum of Bests displayed on my splits.

Update: after several attempts I got the changes to save but it's inconsistent whether the changes save or not.
