* No automatic actions: The game doesn't automatically sell or release your extra horses. They will remain in your barn, even if your sub runs out.
* Limited space: You can only have a maximum of 10 horses in your barn at any time. If you have more than 10 horses and your sub runs out, you won't be able to bring any more horses to your barn.
* No penalties: There are no penalties for having extra horses in your barn, even if your sub runs out. You can continue to care for them and use them in the game.
Here's what you can do:
* Upgrade your sub: The easiest solution is to upgrade your sub to a higher level, allowing you to care for more horses. This will allow you to house all your horses without worrying about running out of sub.
* Sell horses: If you don't need all the horses, you can sell them at the auction house for in-game currency. This will free up space in your barn.
* Release horses: You can release horses back to the wild by using a 'Release' option in your barn. This option is available for horses that are not in your breeding pair.
Important note: If you are a free player, you have a limited number of horses you can have in your barn at any time. The number of horses you can own depends on your current game progress.
In summary, if you have extra horses in your barn and your sub runs out, you won't face any penalties, but you will be limited in your ability to add more horses until you upgrade your sub, sell or release some of your horses.
