Lost Campaign Progress

[SarcasticCreeper]

I made it all the way to level 25, then all my progress was lost! Is there anyway to recover it? What should I do?

As far as I know, there is no actual way to recover it. Best bet is to redo the campaign up to that point.

Yeah that happened to me before, like 3 times already. I finished all 42 levels, then I went and deleted half the history, then came back next day and see my whole campaign levels rest itself. Tough luck I guess :l *shrugs*

There is no way to recover what you've lost but there's a way to prevent it.

Check out part 1.
If your flash player's settings don't show up the sliding bar over there. Just use this client to play. It works better and saves differential data by time.

-- Campaign Progress Lost --
There are reasons due to which your campaign progress is lost. These reasons can be limited local storage, progress not synchronized properly with the server or playing after a long time. This progress can not be brought back but, however, can be prevented in the future.
SOLUTION :

SET THE LOCAL STORAGE TO UNLIMITED
->Go to the Play Tab from the main site.
->(ON THE LOADER : http://prntscr.com/bwhayf) Right click and select settings
->Select the local storage menu and put the slider to the right-most side http://prntscr.com/bwhb8p

RESET THE LOCAL STORAGE
Problems can occur with your loader's storage or reducing performance ; If the above tutorial doesn't solver your problems you should :

->Go to the same Local storage menu and put the slider to the LEFT-most side http://prntscr.com/bwhc5u

->A screen will prompt asking if you want to continue or not to delete all the stored contents ; Click Yes (Make sure your progress in synchronized before making this step)
->Now Set the Local Storage to unlimited by the first tutorial.

You should reset the local storage by time ; that will boost most of your performance in game.
this might help too http://prntscr.com/bwhdk3
