BUG: Killing the goblin village after accepting the shakedown does not remove the alert

I accepted the goblin shakedown, and when I realized that I wouldn’t be able to gather the resources, I converted all my people to attack units and wiped out the goblin village. The shakedown notice is still in the notices panel and has no way of being dismissed, meaning that the notices button is constantly highlighed.

Steps to reproduce:
Got shakedown alert.
Said ok.
Converted all villagers to attack units.
Wiped out goblins.

Expected Results:
If the goblins are all dead, including the boss, then the shakedown notice should disappear, even if it hasn’t been fulfilled.
