I noticed dungeonloots is no longer showing the instances on the map now. Big bummer. SO I deleted dungeonloots and lootomatic 1.4, cleared cache/cookies and rebooted computer. So I have 0 addons now.
I'm still getting the map file missing error. After further testing I find that this happens when changing zones/maps. When you load the game, the map works for the area you're in. Once you change areas, the map file missing error comes up. An example of this is loading the game in Varanus. The Varanus city map works. Leave Varanus city and pull up the map and you get the map file missing error. Only reloading the game fixes the map. Going to yet another area/map does not fix the map file missing error. So reload the game outside of Varanus city and map works. Head to Logar and the map changes and you get the map file missing error. Then you have to reload again to get the map to work again.
I have 0 addons. This can't be an addon issue if I have no addons. This started when the map started including wow map.
I really liked seeing the instances on each map. That was very helpful. If you can add wowmap to the regular map, then maybe you could add the instances as well?
Hope this helps.
