[CLIENT] Gift a skin to someone under same WiFi network as you for free

Hello Riot! I want to let you know that there is a method to gift a player a skin for free (but they have to gift you back at the same time). Me and my brother both had RP one day and we decided to mystery skin each other, and we are under the same WiFi network connected via wireless. We discovered this bug unintentionally, we took turns gifting each other first and seeing what we got, and then I suggested lets do it at the same time, and we counted down and 3 2 1... we both sent a gift, and one of us got an error, I forgot what the error said because this was a long time ago, but there's an error in red text after you send the gift, and then we both got a skin, and only one of us lost the RP for the mystery skin, while the other didn't. (also, this was in the old client, not the new one we currently have, the last time I did this was probably April or something)

Steps to reproduce the bug Two accounts that are logged in must have enough RP to send a mystery gift. They must be under the same WiFi network as well. Both players must be at the confirmation screen before you send the gift (where you can type in your message, message is not needed) On countdown of 3, both players send gift at the same time Both players will receive a random mystery skin, but only one will lose the RP, (I think the person who clicks first will lose the RP while the person who clicked it second will get the error) Person who loses the RP doesn't receive an error in red text, but the person who doesn't lose the RP receives an error, and can just ignore it and repeat the process.
