We have just released a new version of Hooves Reloaded which incorporates the new Facebook Graph API v2.0 as well as changes to breeding. Some players were finding that their horses were born at maximum strength or endurance, unable to train higher. We have made changes to breeding to increase these trait caps and also implemented a small chance of mutations occurring on particular inheritable traits. These changes will increase the breeding diversity of horses and allow horses to train higher. Please note this change will only apply to horses bred after the patch is applied.
If players have issues with Facebook login or Facebook invites after the update, please try clearing the Hooves Reloaded application data on your device (usually under Settings > Apps > Hooves Reloaded > Clear data). You can also contact support for more help.
