Adventure has ended prematurely

I started the The Island of the Pirates last night 21 september at around 20H00 (EST) and defeated half of the camps when I stopped playing.
This morning, when I connected to the game my adventure was gone.

I received a mail to tell me that the adventure has ended, but I should of have at least 1.5 days remaining to complete it.
I did not accept to experience points, I still have the mail.

Did something from last night maintenance erase my adventure.

Hope to have some news.
Thanks.
