I downloaded the patch and then played a few games where my game crashed at the voctory screen... It just froze, its been happening to many people, I think its a bug too. So I had to force restart my computer and it is making me redownload the entire patch. Rito Halp!
Hope that doesn't happen to me.
I'm running on limited data

all having problems.
It's doing the same for me too. Yo Riot Please help us 
Same happend to me. Restarted the game and have to patch again. With my slow internet it takes so much time so I can't play a single game today.
same here
HOLY FUCK RITO FIX YO SHIT
I have no idea why this is happening. I closed down the client. Then I wanted to get back on to League of Legends and now it's scanning files as if I didn't patch the client when I did in the morning...-_-
It redownloaded once and it's been fine since.
Repair your clients.
I generally don't have problems with the game. Should I just let the client redownload?
The same issue happened to me except my game didn't crash. I logged out of the game and went onto the internet for a bit and then when I opened it back up again, the client restarted the download.
My internet is soo slow, it just took me several hours to patch 
WHYYYYY?
