Game Wont Load

I was trying to make a large playing area on a page, I wanted a map of some sort and made it very large, 1k by 1k (could have sworn I have before). Now the game wont get past 13 seconds to load and I can't find anything outside of loading in to undo this mistake. 

Here are some steps to try out when this happens: Try accessing the game through both Chrome and Firefox. If an "unresponsive script" prompt pops up, try letting things sit for several minutes. If the game still fails to load, answer the prompt such that the "unresponsive script" stops. If the Player Ribbon is on a different Page, you should be able to solve this by promoting another account (e.g. a player or somebody else you trust) to GM. Afterwards, that person should be able to access and edit the Page Settings of the Page in question.

got a friend to do that thanks. Would be a good idea to have an out of game undo option or something though, or a warning about what size is too far.
