1. Yesterday me & my friends completed the bridge encounter, we killed all the gatekeepers when they came out all together and yet the step never completed! We've been waiting for a while yet nothing happened.
The chalice was no longer available for some reason, I think someone took it while I was killing the last gatekeeper...then it disappeared completely but the step did not complete!
2. It seems impossible to get an Ir Yut checkpoint. The day before we quit the game at Ir Yut (I wiped there as well) then the following day (with me being fireteam leader) we loaded into the raid and we landed at Crota!!!
