Okay, looks like they made a change with the check box option on the world map ( in full screen map version only - at least now ).
WorldMapFrame.lua - 5.2.0
Code:
221. WatchFrame.showObjectives = WorldMapQuestShowObjectives:GetChecked();
WorldMapFrame.lua - 5.3.0
Code:
239. if (GetCVarBool("questPOI") > 0) then
240. WatchFrame.showObjectives = true;
241. else
242. WatchFrame.showObjectives = false;
243. end
244.
WorldMapFrame.lua - 5.2.0
Code:
341. elseif ( event == "DISPLAY_SIZE_CHANGED" ) then
342. WorldMapQuestShowObjectives_AdjustPosition();
343. if ( WatchFrame.showObjectives and self:IsShown() ) then
344. WorldMapFrame_UpdateQuests();
345. end
346.
WorldMapFrame.lua - 5.3.0
Code:
362. elseif ( event == "DISPLAY_SIZE_CHANGED" ) then
363. if ( WatchFrame.showObjectives and self:IsShown() ) then
364. WorldMapFrame_UpdateQuests();
365. end
366.
Doing the following slight change to :
Plugins/nUI_Location.lua
Code:
-- Xrystal 5.3.0 Change - No longer need this change as function doesn't exist and blizzard doesn't adjust position anymore
--hooksecurefunc( "WorldMapQuestShowObjectives_AdjustPosition", SetLocationAnchor );
nUI_MapLocation:SetScript( "OnShow", SetLocationAnchor );
Will stop the error message from appearing, and no apparent difference to the display.
