Mobile players can follow these steps to resolve this:
- Load the saved game with problem.
- Go to the Pause Menu.
- Select the "Redeem Codes" option.
- Choose "Redeem Other Code".
- Redeem the following code: wgqu@qmnz
- Redeem this code as well: puck@howe
- Go to the world map and the next location should be unlocked
Unfortunately, this workaround is not available on some versions of the game - if these steps have not helped, we encourage you to load an older save file before proceeding in the game.
