Since yesterday I have been unable to get to open Tier 5 of the game. I am able to:
See Start screen
See "shop", where I can upgrade bike and tricks
See US map
Open Tiers 1-4
Tapping on Tier 5 still displays the menu bar (back button, gas, energy, level, etc.), but the content area is empty/black. What's the deal? Can I expect it to work soon?
Also, for quite some time, I have been unable to get to the leaderboards.
