It's impossible to properly finish this quest and earn treasury notes.
For those who may not know to finish this quest properly and claim your treasury notes you must kill all the mirelurk before they reach the island. If you dont, then the mirelurk queen will spawn and you lose out on the treasury notes. It's impossible to do this because no matter what a mirelurk will spawn on the island now instantly calling the queen.
Many players may not even know because it says you finish the event after killing the queen, but in a proper play through you won't even spawn the queen.
I saw just now from another reddit post, that on discord they announced they were taking the messenger event offline because of it not working properly, so I thought I would bring this to thier attention and I don't use discord.
