While I was playing the quest mode, I found something strange, and it borthers me quiet a bit. Here is the problem, my quest mode Merisiel and Kyra gain Card feat tier 1 eight times after they have reached lv10, and now they are in lv21 and I have unlocked everything on their card list except for 1. However, my quest Amiri and Lini,(both in lv15) got Card feat tier 1 only once. Is that normal or I mess with some horrible bugs?
