Stuck at base

I was playing in a ranked game, Orianna. Loaded in later than usual, which is sort of ok with me considering that I’m using a mid-2009 macbook pro. However, I was able to walk out of the circle of the base. It’s like as if there was an invisible wall around the base. When i tried to flash past the steps, it would automatically force me back into the centre of base, as if I was dc’ed from the game. I had to restart client in order to fix it.
