I have a strange problem with Rules. I try to set up 2-directional entity references. It works well with one content type, but fails with another. In the latter case, saved node is not converted into node when used as parameter in action like "Set data value" and Drupal tries to save it as array (which fails, of course).
So the questions is: Do you know about something (field, content type setting), which prevents Rules from properly converting saved object?
I'm using latest Rules dev from Drupal 7.
