my native res is 1680x1050 i run D3 in 1600x900 for it to work (fullscreen-windowed). I literally tried remaking OldRuins.png a hundred times and its in the right folder.
Funny thing is that like 4-5 hours ago it worked past the oldruins spot but it didnt enter the cellar (correct movementspeed and all). But then i deleted everything and tried from scratch. No luck since.
edit : i think i tried making my desktop resolution 1600x900. Will do that again
