Cant understand

At my hunter island online mission information it says that the mission goes until today, but it is still there and the next one was not announced, why??

it wont be removed till next mission usually runs longer than said

Yeah lol They need to do something om that although the prizes Will probably be claimed already

So why does it say that the mission is availae until 19/12??

Because that its a weekly mission and the week ended at the 19th
