I was currently come across this issue, I can not save a openstudio file by using both the Openstudio stool bar saving and extension Openstudio export. When I click save, no error pop up, but the new file created. But I have no problem in export IDF file. I was using Sketchup 2017 with Openstudio 2.3 under Windows 10. If you have any idea about why this happened, please help me out. Thanks a lots.
