Link disappears when ungroup


I have a problem when I ungroup two nodes that are in two differents groups : the link disappears and I don’t know why.
If I link nodes before to group (swap steps 2 and 3), when I ungroup, the link does not disappear (that’s ok).

Do you have an idea how I can fix that ?

That’s a bug inside GraphLinksModel. Thanks for reporting it. We’ll produce a new DLL soon.

We tried the new dll and it works now.
