Hi Felix, hm, in that case one of the two factors is already negative. You can enable logging and run the combiner step again (no need to compile the tiles again) Add this to the log config: uk.me.parabola.imgfmt.sys.ImgFS.level=FINE BTW: The index contains not only address search data, also POI.

The code line is file.position(param.getReservedDirectoryBlocks() * param.getBlockSize()); so two ints are multiplied. Please try if the attached patch changes something.

It went through fine on all geofabrik country extracts.

I'm going to run with default style now again - to see if it makes a difference.
