Could you please try to clear Cache of the app from the settings of your device?
You need to go to Settings -> Application Manager -> Age of Lords (tap it) -> Clear Cache
If your Age of Lords account is secured with an email address, you can even uninstall the app and install it again. This will give the app a fresh start and you should not experience any inconveniences. Please make sure that your game account is secured with an email address otherwise you might temporarily lose it.
Also, please note that clearing your RAM memory might also help the game run smoother on your device.
Let us know how it goes after proceeding with these steps.
We wish you a most wonderful day ahead and all the best in you future endeavors!
