Replays Keep Crashing

It was fine before, but now the replay system keeps crashing. It got better this patch, but still crashing quite often.

Basically, if you first start up replay and tried to skip somewhere far into the game, it will crash. If I skip too much at once, it will not display any champions, and then it crashes. I need to skip little by little till the very end to get to the time frame I want.

The back button used to work, now it will crash 100%. The only way to go back in time in the replay is by using skip timeline.

Recording function sometimes crashes as well. I think if I tried to record after the game ended (then skip back to a time when the game didn't end), it will crash.

I am not sure if it's just my computer or does it happen to other people as well?
