I am having the following problem. In chapter 12, I cannot finish the task named "fear itself" which is defeating Skirn. I ve killed her a couple of times but the task doesnt get registered as finished and i dont want to waste 10 gold to skip it. anyone else having the same problem? could it be caused by the trainer?

The way PD is giving out gold is really suspiscious. I think a major update should be coming soon. Maybe the new season? now the Worthies came to their end, Who would be next? anyone has any ideas?

Are you using Skip Fight/Autowin? If yes, that's the reason.
..
Also, about the new stuff. I really hope they bring Silver Surfer and the likes to the game. My only concern about Surfer till now was Galactus. That thing is  too friggin' huge. However, since they showed us serpent, they can probably do Galactus as well. I would love Surfer. 
.
BUT, Surfer *should* be a damn Overpowered hero. So, it would be best to give him through something special that requires around 500 gold or 1000+ CP. I know it's a farfetched idea but that will justify the insane amounts of gold and CPs we are getting in mission 12.

Autowin didn't count for me either, and it was all I had enabled. I'm guessing something has changed. 

There is also 350 Gold total rewarded for SO36 tasks 3, 9, 12, 16, 20, 23, 25.

This is how we know Playdom/Disney is not messing around and will shut down for real.

If you read the gaming news, the staff responsible for developing MAA1 (Playdom people) have been served the notice by Disney Interactive. And since it's a big franchise, they won't be releasing the code and hence no prospect of the game being continued by fans.
