Piece designs update in XXL chess?

I am a fan of XXL chess and I play it frequently. But today I opened an XXL challenge from the lobby and got these different piece designs:Is this an intentional update or some glitch?
 

IDK

Your piece theme must have been changed to Neo. You can change it in the settings.

ooooooh

Yes I remember doing g it

I will check

your piece theme got screwed up. you can fix it in settings.

Thank you, I didn't realize that there was a legit difference between the Neo and Standard piece set as they look the same in settings.

Dude I have played XXL chess but I don't know how to win this mode but this chess updated is sooooo funny version of chess🤣🤣🤣🤣🤣🤣🤣🤣🤣
