[Gameplay] Gradually Unresponsive Character

So far this game that I am in now is the only game that I have experienced this. Basically, the game starts out normally but within maybe minute of moving around, my champion (Thresh) starts responding slower as if I am having a high ping, and stops moving all together. However, the ping and FPS is completely normal, every other aspects of internet was functioning and I could see everyone moving perfectly normally. I have confirmed the latter fact with the duo que partner who was moving around to see whether what I was seeing was what was actually happening. This resets however when I restart the game or I die and respawn, but persists again in about a minute. Also if I leave the character frozen it sometimes returns to moving after a prolonged period of time.
