short footway=crossing, shorter than guessed road width are causing issues

https://www.openstreetmap.org/way/561900089 and touching crossing ways is/are unexpectedly crossing with road area not exactly two times (or even even count) but 0 times, which is unhandled something went wrong. If OpenStreetMap data is correct here, then this is a bug, please report to https://github.com/matkoniecz/lunar_assembler/issues

From what I can see the OpenStreetMap data looks reasonable?

Thanks for report! Yes, OSM data seem fine here.

Do you remember which map style you used? (I should include it in an error message)

Though https://www.openstreetmap.org/way/197017783 seems quite narrow on aerial view - is it maybe a service road rather than unclassified? Maybe even alley or driveway?

I'll go take a picture of the road later. It's likely not an alley. Japan has lots of "two lane" narrow roads. Could be residential whatever that means.

I didn't change the default settings.

So there are two parts here

1. stop crashing and generate something
2. produce nice crossing also in such case (by extending such line and making it longer)
