Game Nexus Fountain Bug

Hello!

Firstly, this bug is not crucial and has not affected my normal games in anyway, but I thought that it was strange enough to be mentioned and should be reported. On approximately 3 separate occasions, when I load into the game, I purchase my starting items, and when i exit the store, I see my champion running it down mid, or anywhere else, while my teammates are still blocked by the 15 second wall. Obviously this small advantage outside of the base means nothing, but I know it shouldnt be happening, and I even did first blood invading with my small head start. After leaving the base, I was able to move anywhere on the map and function properly. I doubt it will have any effect on the game, but I thought it has happened enough times to me that it should be mentioned.

TL;DR, my champ runs out of the base before the nexus walls drop at 15 seconds or so.
