Gamma13 rollback

Hi everyone,

I'm very sorry, but we've had to rollback to gamma12. Soon after the update we got reports from a number of players about crashes. We've had a look and it's something we need to look more into.

If you were playing gamma13 without any problems then you can still get to it on the test branch. To do so, from the Library tab: right click on Mini Metro, click on the Betas tab, select "test" from the dropdown, then click on Close.

Sorry again for the issues, we hope to have it back up and running soon!
