Okay so I was just playing a bot game on TT and was trying to land a skill shot on a fleeing enemy.
WHEN I LEFT CLICKED, I HAPPENED TO ACCIDENTALLY OPEN THE STORE.
What I'm trying to say is, you can enter the store, THROUGH the enemy base version of the store. I'm pretty sure that you cannot buy anything without being on the summoner platform. But the point is that it was an accident that, if it had been a PvP game, with me that close to their main base, a myriad of TERRIBLE things could have happened. Like dying.
Since we were winning so hard I had enough time to try it multiple times and make sure that was what triggered the store. And it was.
So either make it so that doesn't happen if you happen to click on the store..... or change it so I can buy from the enemy store without being on their summoner's platform.
