Missing output for some tiles

[ktjaco]

Hi,

Thank you again for this tool. I was able to get a model to generate an output on QGIS 2.18.3 for the positional accuracy on road networks (buffer analysis), although some of my regions of interest did not calculate the inBufPerc.

Here is an output using 5m buffers. As you can tell tiles 203 and 223 did not perform buffers around the reference road networks or calculate line length for inBufPerc. I was wondering what may cause this? Would it be the "Remove Null Geometries" algorithm?

I've also attached my .model file.
