A list of known bugs that plague the client (and have for years)

I'm just going to post this so hopefully others can upvote it and maybe Riot will see it so they can prioritize fixing their really bad client in the coming patches. Most of these bugs revolve around champion selection but there are a few bugs in game and outside of champion selection (but within client).

1. Selecting a Champion to ban randomly prevents you from banning them. After the ban timer runs out you are either returned to your lobby or disconnected from the client.

2. The timer that determines the time that you have to select champions will run out and remain at zero; depending on when this occurs, it will either force your party back to lobby or cause you to be delayed in picking your champion until the issue can resolve. If you weren't picking your champion when this happens, the client will briefly disconnect you and reconnect you with a timer that displays the incorrect time. If you are choosing your champion when the timer runs out and stays on zero, you will be frozen in the client and will be forced to log out.

3. Sometimes you cannot choose a champion and timer will run out, forcing you to restart client.

4. When entering shop after purchasing RP, the client will occasionally inform you of its incapability to load the store and will force you to restart the client to fix.

5. Client will disconnect after a queue timer pops up. You can click accept but the client will not accept. Forced client restart is required to fix.

6. Client will randomly disconnect your party members from the queue but leave you in queue after a queue pop up failed to accept all players. You will remain in queue while your party members wont, if you get another queue pop and accept it, you will be removed from the party and placed into champion selection without your party. This will occasionally cause crashing.

7. Personal messaging friends both in game and within the client will inform you that the player is not on your friends list and refuses to send messages. This happens in game more than in the client, but has happened in both to me.

8. Disconnecting from chat while in champion selection will cause client to randomly desync and require a full restart.

9. Client will sometimes add a player instead of blocking them and vise versa.

10. Building item sets will occasionally disconnect your client if the item is ranged or melee only placed within a set created for ranged/melee champions.

11. Re-rolls within ARAM queues can become infinite if re-rolling in the middle of a disconnection.

12. A player dodging the champion selection queue may cause you to receive a leaver penalty of 5 minute wait times, even if you aren't the one that dodged.

13. If a player in your party dodges the champion selection queue you may receive 5 minute wait penalties if queuing by yourself.

14. Choosing a ward skin while still choosing your champion causes a client desync which disconnects you from the selection, forcing a restart.

15. Leaving client open while game is running sometimes causes the game to crash and you being unable to join back.

Please note: These bugs cannot be fixed by Hextech repair tool or repairing the client. I have tried numerous times to repair these fixes myself to no avail. Riot themselves need to fix these issues.

edit: Forgot a bug.

..16. A bug occurs sometimes after a disconnection and a re-connection during champion selection where you can choose ward skins before locking in your champion.
