Hi Martin
You can download the splitted tiles here:

Thanks, this is very helpful.
I think the problem is that I am missing the case where the same street
is in different map tiles when creating mdr20.
I attach a new version of the patch, afraid I will not have time to do
any testing or changes to it over the next few days, although I do have
high hope of it being an improvement.
