@JamesPike,

I have worked with MPP file using Aspose.Tasks for .NET 20.6 and have been able to observe the issue. A ticket with ID TASKSNET-4210 has been created to investigate and resolve the issue. We will share the good news with you as soon as the issue will be fixed.

The issues you have found earlier (filed as TASKSNET-4210) have been fixed in this update.
