Computer freezing on login is linked to the bot friend request.

So after having my LoL client crash every day for the past few weeks I finally figured out why.

It's the bot friend requests, something about the way riot has friend requests delivered must be overloading the client on login. When I watched it, my client crashed I connected to the chat server and friend requests were delivered. This also explains why relaunching the client it resolves just fine, because the friend requests are no longer being delivered they have already been received.

Now this could all be bullshit speculation, but I started noticing the client crash after the bots started to get worse. I think this is at least worth looking into for riot.

TL;DR: Client crashes the moment you connect to the chat server and friend requests are delivered, explains inconstancy among other things.
