[BUG] Draw map function doesn't work when drawing bus routes + metro

[Bohaska]

Describe the bug
I'm on a Mac, so this may be only occurring on my end.
When I tried to draw a map with several bus routes and 1 metro route, the HTML file loaded, but the legend to the left and the map to the right was missing. After I removed the metro route and generated a new map, the draw map function works.

To Reproduce

1. Go to a city with both a bus and metro network
2. Go to options, draw map
3. Open the map
4. See error

Logs

When checking browser console log, I found this error in the faulty map, but not in the working map.

The below maps are the same network, the only difference was that one has a metro network, the other doesn't. These files are in a zip file, Github doesn't allow sending HTML files directly.
