Riot Games has removed the most recent Dark Star login screen from the League of Legends client after a user reported that the animation resulted in an epileptic attack.
According to Redditor
"I'm so sorry that happened. I'm gonna PM you. We need to keep this from ever happening to anyone," Redditor The_Cactopus wrote. He soon updated his comment, saying "UPDATE: We've replaced the Dark Star animated login screen with the MSI login. The change is
"HEADS UP: As of now, Riot just changed they login screen animation to old MSI one, so big thanks for Riot for quick reacting and solving the issue! I am very sorry that I bothered Riot with this,"
Riot didn't seem too bothered though as the Riot employee also noted within the thread that the company had special software in place to detect issues such as this one before certain updates go
Within a few hours, Riot also put out an update on their Riot Games Support Twitter account to let users know the state of the login screen and the progress on resolving the issue.
We've heard reports of the Dark Star login causing issues. We are moving as fast as we can to remove the login while we investigate!— Riot Games Support (@RiotSupport) May 5, 2017
The login screen that caused the issues followed the MSI login screen to showcase the new Dark Star Orianna and Dark Star Kha'Zix skins that were recently released in Patch 7.9. It depicted the two champs emerging from either side of a dark mass with simple movements punctuated by jarring flashes of light and sudden movements. The video has also been removed from the League of Legends YouTube account, and there's no word as of this time whether the login will be reinstated.
