Gameplay bug

Okay this has been happening for a couple weeks now and I thought that the next update (which has happened) would fix it. I also havn't seen any other people complaining about this on the forms, but here it is. Whenever I start a game (after champ select) the game will start to load the screen with everyone's champion and their summoner spells. But then a message pops up and says that I have disconnected. So I press reconnect, and the same thing keeps happening until the game has started. Then once the game has started and I press reconnect I am brought into the game. I play draft, aram, any weekend gamemode and it happens to me in all of them. This isn't ad much as a problem as it is an annoyance. Plus since I get into game late I don't get that starting run boost. I have no idea why it happens and I just hope that it can be fixed soon. Thank you and good luck.
