The quest Memory Alembic requires a player to obtain 8 Qualichors to create a Refined Qualichor. It is a two step quest which allows players to then use the Refined Qualichor to open a chest after a successful Lucent Hive event and finding the chest spawn. However… I found a game breaking bug which cripples a players ability to do this repeatable event quest. If you begin the quest on one character progress is contributed to that characters Memory Alembic quest each time you do an investigation or lucent hive event. On any of your characters as the Qualichor collected for the first time doing the quest is placed into the quest itself. However if you complete the quest on characters who are not on the quest itself the problem arises that they will receive the Refined Qualichor to open the chest and the main character who is on the quest gets a completion of the quest but it doesn’t give the 2nd step despite the Refined Qualichor being obtained. This puts all of your characters on your account into a state of limbo after recieving the Refined Qualichor. You are able to open a single Lucent Hive event chest but afterwords the game believes you have already done the Fynch step preventing you from restarting or continuing the quest you will stay in this limbo holding a basic Qualichor in your inventory and another in the mailbox at max. And you will be between steps unable to start the quest anew on a new character and unable to actually complete it on your main. You will never again be able to participate in this event and have two item slots permanently filled unless you constantly delete them as you obtain a non usable Qualichor.
