I ran the Raid for the first time with some people off of the forums yesterday. It was a lot of fun, but a checkpoint error made us miss a loot drop. What happened is that we made it to the Gatekeeper, but most of our group had to leave very soon. We gave it a few tries, but we kept wiping because of the enemies in the portal. So we decided to abandon it for the time being. About three hours later most of our original group was online again, so we grouped up, found two more to fill out our team, and jumped back in to the Vault. But when we spawned in Atheon was already standing there waiting for us. We had not gotten to Atheon in our previous play session. I was happy at first that we didn't have to do the Gatekeeper sequence, and we managed to defeat Atheon in about 40 minutes. But after finishing I went to the companion app and noticed that I only had 3 out of 4 bosses looted. After looking around the forums I realized that the Gatekeeper sequence gives you loot after its completion, but that our checkpoint glitches and made us skip it. Please separate the Glass Throne checkpoints into two distinct checkpoints- one before entering, and one after defeating the Gatekeeper and looting it- to prevent other Fireteams from missing out on loot.
