Greetings Summoners!

With every new patch Riot introduces to balance out champions and items there are some unforeseen issues that creep up and cause disruption during gameplay. We have noticed that these issues which eventually get fixed clutter up the subreddit immediately following the patch.

We want to avoid this by having a single Megathread which will be posted after every patch so that you guys can report the various issues in one place. This allows Riot to easily keep track of the bugs by providing a central hub and also allows other users to confirm that they might have encountered.

Note only bugs caused by the 11.21 Patch should be reported below.

Prerequisites to be noted before reporting a bug


  1. A bug will ideally be accompanied with a screenshot or a video. This provides credibility to your report.
  2. Steps to recreate the bugs should be submitted if possible. This helps Rioters recreate the bug and helps them find the cause behind it.
  3. The bug must have been caused by the latest patch.

Format when reporting a bug: When reporting a bug, please provide as much information as you can about your computer.

Server: The server you encountered the bug (NA, EUW, EUNE, TR, RU, BR, LAS, LAN etc)

Type of Bug: Client Bug, In Game Bug etc

Description: Describe what was the bug that occurred.

Video / Screenshot: Insert screenshot (F12 in game) or Video of the bug occurring.

Steps to reproduce: Provide the steps necessary if someone else had to reproduce the bug.

Expected result: What should have been the result when you follow the steps mentioned above.

Observed result: What was the result you obtained when you followed the steps mentioned above?

Reproduction rate: If you try to recreate the bug how successful are you in causing it to occur? (1/10 : Occurs once every 10 tries, 5/10 : Occurs 5 times out of 10, 10/10 : Happens every single time)

System specs: Processor, Video card, Ram, HDD/SSD, everything you can provide, even drivers.


Example Bug:

• Server: EUW

• Type of Bug: In-Game Bug etc

• Description: Zed's R(Death Mark) does not apply secondary damage

• Insert Video / Screenshot of the incident

• Reproduction rate: 2/10 (happened 2 out of 10 times)

• Steps to reproduce:

Launch a game after selecting Zed as your champion. Attempt to use Death Mark. Observe the result.

• Expected result: The damage should apply after a short delay, amplified by damage dealt during the effect.

• Observed result: The damage will not apply properly.

• System Specs: Intel i5 Processor, Windows 7, Nvidia Graphics card (insert model number) etc.

Type of Bug: Client and Game bug

Description: The lower side of the screen (around 20%) can't be clicked, the mouse loses focus of the window. If Fullscreen mode is activated when playing, clicking any part of that section of the screen can minimize the game. On the client, it's difficult to click the buttons to edit your runes or to "Play Again" after a match. On the game, it's impossible to click your own abilities and you can have difficulties trying to move the camera to the south.

Steps to reproduce: always on the client

Reproduction rate: always since the patch is up

System specs:

AMD Ryzen 5 PRO 2400G with Radeon Vega Graphics 3.60 GHz
GeForce GTX 1050 Ti

RAM 16.0 GB (13.9 GB usable)

64-bit operating system, x64-based processor

No pen or touch input is available for this display
Windows 11 Pro
Version 21H2
OS build 22000.258
Windows Feature Experience Pack 1000.22000.258.0

Hmmm I've seen reports like this before but I don't think it has to do with the League or Game client. Could it be a windows issue?

EUW, my client is has just closed 2 times during champ select on its own resulting into 2 dodges that made me lose master promos. Anyone else has same issue?

Did the client crash and you had to reboot it? Was Riot client still open when this happened?

Yes I had to reboot as if I am just starting to play. A complete crash on its own without a warning or anything.

Was Riot Client still open? Like if you were to have 'stay signed in' unchecked, would it have you login again or would you just see the play button in Riot Client?
