The problem is when date is changed we connect to source ex. dilbert:2018-11-14 but in other hand script (main.es) makes

if (comic.identifier.toString() == date.currentDate().toString()) {

comic.requestPage("http://dilbert.com/", comic.User, infos);

so provider do its job but dataengine does not have a data for us, cause identifier is dilbert: and we are not connected to, so dataUpdated is not called which cause busy indicator to eats cpu power. Another fix can be to have permanently connection to comic_name: to enter dataUpdated in any case.
