The Questie version 2.0.5 found here: http://www.vanilla-addons.com/dls/questie/ shows quest icons in the minimap as well as the larger map. The latest version (3.0.7) does not display map notes in either the minimap nor the larger map even when /questie mapnotes is on.

Fix Questie to show minimap and larger map icons once more.

Have you deleted the 2.0.5 Questie folder when you added the 3.7.0 !Questie folder?

Heh, I actually installed 2.0.5 after 3.7.0 did not show map icons. I installed a vanilla wow 1.12.1 game and then immediately downloaded the latest version of Questie. For whatever reason I just tried this again and this time all minimap and map notes now appear!

Closing this ticket as it doesn't look reproduce-able.
