Stamina Refund Feature When Rewinding a Chat

First and foremost, there is an unresolved issue where AI replies stop midway and the full text is not displayed. Furthermore, even in such cases, the standard amount of Stamina is still consumed.

If this issue cannot be resolved technically, please implement a feature to refund Stamina when the chat is rewound.

If this is applied only to the most recent reply, the loss should be minimal.

Please be aware that, as it stands, you are passing the burden of this loss onto us, the users who are paying for the service.
