A new batch of skins were just released a few days ago.
All the skins changed?  And if they did, how much extra would it take to include them in the update?
See, without wanting to pick a fight with you personally, your response screams out what is wrong with the system.  I do not care that a new batch was released a few days ago, when logging in and I receive a message that the game needs updating the I expect it to be updated.  Not some of it, ALL of it.
Is that so hard to understand?
