what browser are you using? Can you try using Ctrl + F5 to reload your cache? It looks like an old game or version is overriding this one in your browser.
And you're playing the browser game and not any of the downloadable versions, right?
I'm due to make a new update / add new contents to this game in a day or so (likely this Friday) - I'm pretty sure it's some weird saving bug that might be using an older update for some reason. If the new game still has this bug, please try playing it on a different browser and seeing if it's got the same error? There might also be a few incompatibility things with browsers that's the issue, but I have to eliminate all the possibilites first before I can focus on which one!
