Client Bug Leads to leaver buster.

During an Aram game, my game freezes. i check if it's my internet and my internet is fine. I try to relog and before i can sign into my account it says "failed to update" which is bizarre since there wouldn't have been a patch between the time of my disconnect and my relog. I try to relog 4 times and it says the same thing over and over, so i give up and do something else. I try to log in the next day and it works, but now leaver buster is warning me not to leave games.

This isn't the first time i've dealt with this bug, where i can't relog due to a "failed update". Since i'm facing a leaver buster penalty, this is the first time im taking it seriously.

Anyone else have similar experiences with bugs?
