Map Node Bug -- Completion Erased

Last night I completed a few endgame map nodes near the haunted mansion. There is an issue where upon logging in the next day, the second to last one I completed has been changed from Completed to Attempted.



As shown in the image, the Stronghold map (left of current location) is marked as Incomplete and when selected it is tagged as Attempted. However, you can also see that the following node Spider Woods is Completed with no other access points.

Summary

Expected Result - Completed map should be green and completed upon continued play.

Actual Result - Completion credit removed, map now marked as Attempted.
