Couldn't leave base

I was playing a game of ranked and my computer was going slow but I loaded in on time. Once I got in I tried to walk out of base and it wouldn't let me, it was as if the gate at the start of the game was still there. I tried flashing out and that didn't work. I left the game and tried to come back to see my team remade, I lost 20 lp and got 5 leavers. A fix would be quite nice.
