Hello there,
Today API stopped returning id field for “border” element of guild crest. I’m fetching this response via the guild profile API. This is happening on a lot of guilds so if you want a sample I can send, but I guess this field is generally missing. Hope you bring it back 
{“emblem”:{“id”:95,“media”:{“key”:{“href”:“api blizzard com url/data/wow/media/guild-crest/emblem/95?namespace=static-9.0.2_36532-eu”},“id”:95},“color”:{“id”:10,“rgba”:{“r”:9,“g”:42,“b”:93,“a”:1.0}}},“border”:{“color”:{“id”:7,“rgba”:{“r”:0,“g”:103,“b”:31,“a”:1.0}}},“background”:{“color”:{“id”:49,“rgba”:{“r”:255,“g”:255,“b”:255,“a”:1.0}}}}
Thanks for your support…
