Major 5-Star Legendary Gem Selector Bug

This selector box is one of the items from the $199.99 bundle during the Chinese New Year event. I have been holding this box until now. After today’s patch, there is a brand new option, with a sword icon and absolutely no descriptions. After choosing this option, the box disappeared but I did not get any new gems or items.

Here is a video of the entire process. YouTube link: j8WSfkvNZ6Q
