The first quest in Reclaiming Europa: Sabotaging Salvation is bugged. Specifically at the point where the team must loot a power cell and throw it at the door, the instance stops, throwing all players to orbit with the error code Calabrese. This not only is a showstopper for this quest, but as this quest is a required objective to allow other Europa quests to proceed, particularly those leading to Exotic weapon rewards. Lost Lament and The Stasis Prototype are at least 2 other questlines which cannot proceed without this quest, not to mention the rest of the Reclaiming Europa campaign which follows it. As a gateway to a large amount of other content, having a showstopper here is particularly lamentable and should be looked at with some urgency. Certainly before any of this content is rotated out.
