Missing ABP Notice On Stone Wall

Version: 5.0.26139.0
Playing the Malian Mastery. Built stone wall on Boulder Bay map. Where stone wall butted the cliffs lime green box with Missing ABP is displayed. The remaining stone wall is constructed and displayed correctly.

Has happened during two game plays; All-Nighter and Underbrush.

Thanks @WizenTube070071! Should be a fix coming for this one.
