"Location missing required itemType information" when opening plan in Kanban view

2) Edited the view and added the related artifact link to the largest card display

3) Saved the plan - this worked fine

4) Opened one of the items and added a related artifact

5) When I went back to the plan I got this error and the plan would not load:

I am using RTC 5.0.2, tried Chrome & Firefox browsers. Can anyone else reproduce this? If so I can submit a defect.

Thanks
