My own games gave a 404 message despite my not having changed anything. It looks like a number of other games have the same issue, that previously valid links are now no longer working. I found that using the dropbox client to access my files fixed things but I’ve no idea what it fixed since nothing was changed in my events.
I had a quick glance at the dropbox site a couple of days ago but couldn’t find a reason why this was happening. Since a lot of other games have gone down too does anyone have any idea what’s up and how to avoid it happening again?
