We are testing a fix for this now, sorry for the inconvenience in the meantime.
Would just like to report a while ago I wasn't able to pick Akali due to this bug, I could choose anyone else (I tested about 20 rapidly) so mehhh.
She's one of my mains, I have 2 of her skins etc so it wasn't to do with rotation, thus why I'm making this post.
