Game no longer working

So, I took a break from Fantasica, and now I can't open it. It goes to the loading screen, and when the "connecting to network" text moves off-screen, it crashes. I've tried uninstalling and re-installing already, but it didn't work.

I'm on iPhone, and in "about" it says it's version 6.1.6. Can anyone help?

This sounds similar to an issue I have with my iPad. Shutting down the iPad tends to resolve the issue (for a while). No idea if it will help you, but good luck!
