I was trying to finish the invitation quest so that I can get other characters levels up after completing it. I got to the part where it wants you to do a run in the menagerie but when I went in it joined me to a already in progress run of some other lobby in which they were already fighting the final boss. I stayed and we completed it but at the end it gave me the reward but did not progress the quest. I have found online that you have to go back into the chalice and upgrade something with imperials but it shows that I have no imperials and nothing to put in the chalice at all. Also with that the menagerie is also not accessible to me as well now. I figured that might be to do not having anything in the chalice to start with. I just want to know if this is a bug or can it happen and what I should do to progress this quest to completion since this is seems like the last step for the invitation quest? Any answers would be really helpful I am very new to destiny other than playing the campaign at launch on PC.
