+/****************************************
+ * Author: Blade Barringer @crookedneighbor
+ *
+ * Reason: Collection quest data on the client is unreliable
+ * because the quest key on the user.party.quest.key property
+ * is unreliable. We were calculating the quest items found
+ * at the time a drop was created, when instead we could
+ * just calculate it from the party on the server. This
+ * necessitates changing the property type of party.quest.progress.collect
+ * from an object to a number, hence this migration.
