The patch excludes the boundary relations from the multipolygon processing. This can be changed with the new option --process-boundary-relations.
This might solve the actual problem, but I think it is a dirty hack. When we have the next tag with such a problem, will we add another option switch?
Instead we should look for a cleaner solution, where either the mp processing can be better controlled via a style file (e.g. a new style file applicable tags for the mp-processing or perhaps limit the mp-processing to the expressions listed in the polygon file), or where the results of the mp-processings will be marked, so that the original and the artifical polygons can be distinguished in the following processings.

I agree that we should look for a cleaner solution. But at the moment we don't have one. It will take some time until we have a reasonable solution for this. I started with an idea to tag all polygons created by the mp processing. But I think that's too complicated for the style file. Please start a new thread where we can think about how the new tag handling of the mp processing and the connection to the style system should look like. I am happy if more than two of us (I don't have good knowledge of the style system) are talking about fundamental improvements. Just for now I strongly recommend to use this patch until a better solution is ready to use. WanMil
