Missing Shapes while Opening and Saving MS Visio Diagram in C#

Hi Support,

After I open a diagram with Aspose and just save it, one of the shapes is missing in a saved diagram.
Code example:
static void Main(string[] args)
var asposeDiagram = new Diagram(“MissingShapesExample.vsdx”);
asposeDiagram.Save(“MissingShapesExampleCopy.vsdx”, SaveFileFormat.Vsdx);
}MissingShapesExample.zip (34.0 KB)
Please see a diagram where an issue can be reproduced attached.

Note: After I deleted sub-shape “Text callout”, everything works without issues

Thank’s Philip,

I tested this version and can confirm that issue no longer reproduces.
When this version will be available under nuget packages?


The fix will be included in the next version i.e. 21.12 which will be released in December 2021.
