Hello Havesterify, somewhere in your edits the Duin en Zee-cycleroute has been changed in OSM so that it goes through the centre of Wassenaar (Duinrellweg) which is incorrect, in reality the signed route goes around Wassenaar along the N441, as it was originally mapped in OSm. I cycled the route both today and earlier. 
The wrong route is also shown on the website you added to the route in OSM, did you use this site as a source to delete the original course in OSM and add your new course through Wassenaar?

Please also note the changeset comments in #13, 22, 23 repairing other errors

Thank you for replying, best regards
