Same thing happened to me in the guild I play with. Selected Pheonix Dawn and ended up in Stonefall. I hope they fix this and people don't have to wait a week to play with their friends!
• Your assigned team: Stonefall• Your original home shard: Pheonix Dawn• The name of the WvW guild selected: Fellowship of The [KOIN] (before deadline)• A description of the issue: Placed on Stonefall instead of Phoenix Dawn
