League of Legends V10.4

Client

Client
  • Bug Fix: Addressed an issue causing the social panel and chat window to break in Champ Select if certain actions (removing a friend, being removed, being blocked) were taken.

Crash Reporting
  • We have a new crash handling system going live this patch which will automatically collect crash data to help diagnose issues. Crash reports help us improve the game because it alerts us when something goes wrong. You can opt out of the automatic crash reports collection by clicking the Settings (gear icon) in-client. There, look under General and toggle off the option. Thanks for helping us help you! Read more about Crash Reporting on the Player Support website.
Friends
  • Bug Fix: Removing a friend, being removed by someone else, or being blocked by someone else will no longer break the Social panel and chat window.
Login Region Selector
  • Starting later in 10.4, you'll need to use unique Riot Accounts, since the region selector on the login screen will disappear. When you log in, you'll automatically be directed to the server associated with your account (so if you log in using your PBE account, you'll be sent straight to PBE).

Slow Resist
