I have been trying to add a brain capacity upgrade every now and then, now that we have new things to learn. Before I felt like so what, what's the rush. The first one I bought was 55, 000 approx. img. The second was in the 60's. The third, which I just got, and is fresh in my mind, started out 2 glitch days ago at 72,300, and now when I got it was 80,000. Same card. What is this? How high do they go? Does an unlearning card really wipe out a skill? I am upset and need answers. Thank you.
