Solid Edge Pattern wrongly calculated after deleting Partcopy

Part consists of a Partcopy and some features, including a pattern of cutouts:

After deleting a Partcopy, which seems to have no connection to the pattern, one row on the right side is missing:

Pattern feature looks okay with no errors or warnings. Parameters and Options for the feature are still the same. Simply the cutouts on the right side are not calculated/shown.

Solution

We found the following workaround:

a) First switch Pattern from "Fast" to "Smart", then

b) Delete the Partcopy

This will keep the pattern as usually designed.
