My amateur fumblings in your engines.cfg. 
I ran a diff between the 1.2.2, and 1.3.0 config files, as I usually do, looking for changes.
I can see I had misread one of the lines, and it was to do with auto_feathering anyway, and you had disabled it. Sorry, that was my mistake. I think I mistook one pane for the other in Notepad++. 
Iāll re-test the above with 1.2.2 shortly.
