Hmm, i'm not sure. I tested the team memory myself, and it seems to be working as far as i can tell. I will note, though, that the team memory wont update until the NEXT game. So, on game 1, if you set the value to 3, and then read it and print it, it will still be 0. At the start of game 2, it should be set to 3.
Make sure you're reading the value back on game 2+ and not game 1 accidentally.
