Hum... it could be the server then :/ atm i stuck with the reconnect to nonexistent game bug so i can't don any further testing to try and see it it really is the servers issues

I'm having the same problem.
I can't farm properly due to this lag, and it seems as if champions are "gliding" across the map.
Dead minions just stay "alive" and when I die, I'm still alive with 0 health, not ready to respawn.
Everything seems a few seconds late, and this is getting frustrating.
Any solutions please? (The suggestion relating to the Adobe didn't work).

Happening to me now as well, just DCd from a game and can't reconnect

Edit: Today I learned that riot has an error report feature in game, however when trying to send an error report there was an error about the error report. Repeat as many times as you click send report.

Same problem here

Same issue here.

Tried reloading the game, type in password and hear the click of the log in sound and freeze there.

Just had this same problem on a PBE game, Just barely started happening and Ive played a few games before this. Was so sudden.

i can't move at all, it started off in champ select for a ranked game - retrieving data from server.

then i froze in draft while waiting for enemy champ 3 and 4 to pick, nothing happened. tried to relog, nothing. restarted computer and happened to get into the game.

once in the game, i couldn't see anything happen around me at all. died once and had to leave. i really hope the loss is forgiven because there was literally nothing i could do to help it.

had the same today

The problem is still there! Riot, please help us?

Same here, having lag spikes randomly just as you described.

Ping never goes past 150MS and the FPS is as it always has been, 55 - 70, my bandwidth and computer are both fast.

League has also been overheating my GPU / CPU lately, making the fans max out, I took the side off of my computer to let some heat out... very weird...

Riot pls (LOL)
