Problem with opening designspace file

Hi, My workflow includes working on designspace file linked to ufo files. I wanted to include GlyphsApp into my designing process, but app has a problem with opening designspace format:

This is an error that appears when I’m trying to do that

The document “Some.designspace” could not be opened. Error while reading the document: /Users/rafalbuchner/someProject/Some.designspace 
(*** -[__NSArrayM objectAtIndexedSubscript:]: index 0 beyond bounds for empty array)

Any advice how could I open this thing?

Could you send me one of the designspace files for testing.

Sure :slight_smile: . sent

I fixed it. Thanks.
