The other item sources live marked in AddItemToInventoryClientSync's extra info, with the keys and values live sent: - mission and achievement rewards: _Metric_Mission_ID_Int and source LOT 1, the player (225 of 225 live rewards) - activity rewards: _Metric_Activity_ID_Int and the activity object's LOT - vendor purchases: the vendor's LOT and _Metric_Currency_Delta_Int, the coins paid as a negative number (left out when the item costs no coins) - mail attachments: _Metric_Mail_ID_Int64 - traded items: _Metric_Transaction_ID_Int64, the trade's ID Loot::GiveLoot gains overloads that pass them on.
