So the Description for both 1-day and 3-day Ally Quest Completion Events DO NOT list any points for EXPERT level of Proving Grounds or Class Daily Quests (probably Solo 22-hour event also). But they actually DO award points, although not the same between the 1-day and 3-day Events.
Description for Easy/Medium/Hard show those have the same points for both 1-day and 3-day Events. But when I did an EXPERT Proving Grounds run, the 1-day got 800 pts, while 3-day only got 400 pts. Although I was expecting 0 pts from both because Expert is not listed in either of their Event Description pages.
Can you please UPDATE the Event Descriptions. As well as look at why Easy/Medium/Hard would be same between the 2 Events (ie, Hard Proving Grounds shows 180 for both 1-day and 3-day Events), but the Expert Proving Grounds was awarding different amounts between the 1-day and 3-day.
