Yup, I get the same exact thing when clicking the link and had the exact problem making a map, seems to be an intermittent problem.
It was working previously, this just started when I opened thread.
Same result. The map shifts to the left but nothing, no browser messages.
I am having trouble with the City Generator export maps to PNG. I have tried refreshing and reloading the generator and still can not export. SVG and JSON work but not PNG. Help please.
