In Retail, with CW 3.0.4 and In Progress Missions installed, I am getting the following error when I open the [current default] Covenant Sanctum report. It does not matter whether it's by clicking on the minimap button or using a variant of "/script ShowGarrisonLandingPage(2)" to open the window. Loaded separately, neither of them are causing this error.
