I was running the raid with a few buddies as usual. Around the 7th lamp he was kicked, we told him to join back so he could get the rewards, when he hit "Join Game" this happened...
Almost like what happened yesterday at Atheon. We had just finished him off with a lucky sleeper shot on third teleport, clearing challenge and ending the raid (I got Vex!) So we all start dancing and stuff...
Only to succumb to the oracles.
It takes a LONG time on the "Darkness Consumed You" screen, then we get Error Code Salamander, and respawn...
"Raise the Spire"
The entire raid reset on us.
