So, I've played a little bit of minigames lately for some quick SG. More specifically, the Sorcerer one. I didn't even grinded that much, 20 SG at most. Now, it hasn't let me gain any more SG for 3 days straight because "enough is enough". If there's a cap on minigame SG gains, why isn't it specified? How much is it? AND WHEN CAN I PLAY MINIGAMES AGAIN???
