Ziechael, the map is an IronDwarf special from the Dundjinni forums. Search for "craftsman's quarter/city streets" for his link to his hi-res version. I followed the steps. When using Firefox it works completely fine. It's only an issue in Chrome (Version 41.0.2272.76 m) and only for maps over ~600KB in size. I am using Windows 8.1, Javascript is enabled, my anti-virus is McAfee, and all extensions are currently disabled.
