I have same problem
Try with reinstalling the game to get it back on track:
1) First, we need to remove the game from Facebook here: https://www.facebook.com/settings?tab=applications (don't worry, your levels, Boosters, Gold Bars won't get deleted)
2) Clear the cache on your browser: http://www.wikihow.com/Clear-Your-Browser%27s-Cache
3) Close the browser.
4) Reinstall the game by clicking here:https://apps.facebook.com/petrescuesaga
Try also another browser than you currently are using. Recommended browsers for our games are Google Chrome, Mozilla Firefox and Opera.
I hope this helps!
