UPDATE: I re-ran all 3 missions/9 investigations today solo (was solo before also) all in one one shot in order from Library to Metro to Student Union. The issue persists as previously stated. I've come across others (posts in Reddit) that are having the same issue. There's only 1 day left at this point and I still haven't been able to get the Diamondback. Please either fix or gift me the weapon.
I finished all 9 missions with the last Student Union mission today. And nada. No game recognition that I have completed them all. And if you are going to tell me I need to complete a set of 3 in one session... well... sorry. The Student Union missions border on un-playable for me on solo. Guess you developers are just WAY too skilled and it's doable for you. For me it was an often 10+ attempts. And not getting the damn completion recognition was just stupid. I hope you fix this as this is one of the few complaints I would have for the game otherwise.
I finally finished the student union yesterday doing all three "investigations" in one sitting. It's certainly not an enjoyable experience as I too found it frustratingly difficult. All in all the whole Kenly College is really backwards game design.
Needless to say I was extremely excited I could finally unlock that door only to be extremely disappointed because I experienced the exact same problem as the OP. Once I get in that door I will never touch Kenly College again.
Today me and my 3 friends finished together the third part of the expedition (student union) after finishing the other two parts yesterday (library and metro). I had previously finished the entire expedition two times, so this was my third time now, while my friends finished it for the first time with me today. When I did it the first time, I could not access the chapel to get the diamondback but I did access the room and get the diamondback on my second run finishing all three parts in one sitting. So I was not expecting the diamond back on my last third run with my three friends today. I actually got the diamond back also few weeks ago for the second time from Emeline Shaw in the Zoo. So after we finished the run today with my three friends, none of them could open the door to the chapel. All three of them tried but it would not open for them. But for some reason I could open the door and get another diamondback from the chest today. I should mention that I was the party leader both today and yesterday. None of my three friends could open the door to the chapel even though we did the entire run together, all three parts of the expedition as I mentioned. This is ridiculous, I was not supposed to get the diamondback today. So I just dropped it for one of my friends at least. Has this issue not been patched like two or three times already? How hard can it be to fix one freaking item drop?
