This same exact thing keeps happening to me in Dominion, and it's causing my team to lose games. My Internet is fine. I've been the only person on my team experiencing these issues, and my team thinks I'm bad because of something that is out of my hands. What is the deal with this? I haven't experienced any of these issues until several hours ago. I'm not sure what's causing this, but I keep having to reconnect mid-game, and it will be fine for a couple more minutes, and then it will **** out again.
I played like five normal games on Dominion without any problem, and it was only within the past couple of hours that this **** started happening.
Here is a LOLReplay file I managed to find visualizing the bug. What you see on the screen when I typed in /ldsgf or w/e I typed is exactly what I saw before I tried reconnecting and shutting down LOLReplay in hopes to fix the problem. Look specifically at the bottom right tower.
Reconnecting is only a short fix before it bugs out again 30 seconds later.

I refuse to play another game until this problem is fixed (or I learn how to fix it).
