Hi oLastManAliveo, I'm really sorry that the achievement for Flawless Raider didn't trigger. There are a couple different things at play here. Currently, we are aware that there are some issues occurring in the raid. In some cases this can make completing the achievement difficult and we know how frustrating that is. Investigations are currently ongoing about addressing these problems to ensure that strange raid behavior doesn't prevent players from getting their achievement. While that work is ongoing, I'm afraid that we are unable to grant or provide achievements to players. I hope that a future attempt will let you earn that achievement oLastManAliveo, and again, I'm very sorry for this issue.
