I am getting some strange behaviour when I update my older Presenter to Presenter 13 files and then edit an engage interaction. When I hit save and return to presenter a duplicate "copy" of the engage interaction is inserted into my project.
I have attached a screen shot. Note the date and time. Since I still have the old engage interaction, and it seems to have taken the edits I applied, I just delete the new one. Thought I should mention this.
