Casalnuovo di Napoli is the only LAU2 / admin-level 8 municipality missing in Napoli (admin-level 6), Could someone (I don't know how to) kindly create it? ref (ISTAT, Eurostat) 63017
Surrounding municipalities Acerra, Afragola, Casoria, Pollena Trocchia, Pomigliano d'Arco, Sant' Anastasia and Volla.
Thank you very much!

There's a fixme on the airstrip. It's an unlicensed private airstrip, also according to the operator, the adjacent restaurant and their website at https://cortebariani.it/il-parco/
Sorry, not an editor, hope someone can adjust the info.

Ferry Lorient-Groix is a car ferry. But despite having times and vehicle yes it does not compute in OSRM. Can someone kindly look what "else" might be wrong?

Yenişarbademli. According to https://en.wikipedia.org/wiki/Yeni%C5%9Farbademli and https://biruni.tuik.gov.tr/medas/?kn=95&locale=en this should be a district relation, admin-level 6, such would need to be split from relation 1827196

OSM admin relations level 6 numbers 2865044 + 3826851 are duplicate. Recommend to merge 3826851 into 2865044.

https://www.openstreetmap.org/relation/2528207
According to Eurostat and national statistics office there are two administrative regions, Ilidža and Istočna Ilidža, which seem to be combined here?

Relation 3826847 (городской округ Джанкой) is dupe with 2865835 (Джанкойский городской совет) and conflicting on admin-level 6.
As such, and as it is совет and not округ I recommend to delete 3826847 as incorrect duplicate.

Relation 3826845 (городской округ Армянск, Armyansk Raion) is dupe with 2865940 (Армянский городской совет Armyansk Municipality). Conflict as both admin-level 6.
Recommend to delete 3826845 as not Raion (incorrect naming).

Relation 3507143 (Uľanka, wrong admin-level 9) does not compute.
Slovakia (2), Central Slovakia (3), Region of Banská Bystrica (4), District of Banská Bystrica (8), Uľanka (9)
It's neither part of Eurostat LAU2 file (= SK OSM admin level 9) nor shows on https://osm.wno-edv-service.de/boundaries/
Possibly an admin-level 10? There it may be dupe with relation 2265288 = Uľanka, admin-level 10 as part of Slovakia (2), Central Slovakia (3), Region of Banská Bystrica (4), District of Banská Bystrica (8), Uľanka (9), Banská Bystrica (9).
Thanks for removing relation 3507143 from admin-level 9 (sorry, I'm just a user, not a mapper)
