This morning i was playing a match when the notification came up that this was the last ball of this type in my inventory. I bought a new sleeve and went back to my round which only had a couple of holes left. Later, I check the number of balls totaled in my equipment. The total was one ball! Now I don't propose to be a mathematician, but since I was playing with a ball and bought three more, I should have four balls not one. You can check my playing since buying the balls and also you can see on my profile that I bought them today.
While I am at it, why does the "You need some more balls" notification display before I actually need them like what happened to me today? This whole thing smells and I don't like the odor. By the way, I am a Legend with over three years playing this game.
