Hello, 
I think that this edit has broken some relations in Dublin:

<  -10709165 | Monkstown Parish
<   -8851327 | Holy Trinity Kingstown Parish 1900

<   -8856889 | Diocese of Dublin 1900

<  -11298801 | Province of Dublin

<  -15480473 | Killiney DED 1971
<  -12498372 | Killiney ED

<   -4622511 | Killiney
<   -4622479 | Rocheshill
<   -4592163 | Ballinclea
>   -4486085 | Spinans West

<   -4672601 | Killiney

<   -4574127 | Rathdown

<   -282800 | County Dublin

If you download each in JOSM and hit the "validate" button you'll see what has happened and will be able to fix.

Best Regards,
Andy
