Acts_as_list long standing before_destroy bug

Just a comment: It took me hours to figure out that acts_as_list is
the culprit of an erratic behaviour in my model (I am still a newb).
My model changes some other model before_save. Upon destroy, those
changes seem to be reversed by acts_as_list. I applied this patch: . The problem is
solved. I just don’t know why the patch has not been applied to
GitHub - rails/acts_as_list: NOTICE: official repository moved to .
