[Client] Chat glitch

Hey guys, so after I updated my client to the new patch something really weird happened to my in-game client : It is the chat. My chat has been glitching since then and it is extremely annoying. What it does by glitching, is that during a conversation with ANYONE in my friend list, what I say goes all together even though, the answer of my friend occurred before what I said. Here is one example :

Message 1 ( From me ) Message 3 ( From me ) Message 4 ( From me ) Message 5 ( From me ) Message 2 ( From my friend )

As you can see, the second message isn't at the right place, and it's really annoying. Hope someone could help me with that issue. I tried sending ticket to Riot Support but it wants me to sign up and whenever I click on Sign Up, they put me in a website that doesn't load any sign up forms, just all blank. Thanks for helping ! Have a good day everyone and a good season 6!

Also, I tried to logout then back in, but it didn't work. The same goes with when I restart my computer. Add me ingame if you know the answer or reply below ! IGN : Febiven
