Hi, Nik,
The last change I am sure of was creating a partial and then deleting it from the project’s edit pane. After that I tried to undo the deleting. There was a couple more instances, but I don’t remember what I was undoing at those times.
In the last couple of days I did not experience any unexpected quitting. The project is just an exercise/experiment with a new theme, where I just attempt to set the initial look and functionality. There is nothing solid yet about it…
