Errors appearing on all three generators

[Zkaface]

When running the code with several png files i everytime encounter errors like these: "error on line 8923 at column 136: Couldn't find end of Start Tag path"

Regardless of whether I use the sketch, the spiral or the crossed module. It seems, that the generation stops at some point and does not finish the svg-image (crossed is cropped, spiral got a hole in the middle)
