My plan was to max out all N cards and have normal gacha have 100% R or SR on each draw.

I just maxed my all my N cards and when I try to do normal gacha, and land on lvl 100 N card, the prize is not an upgrade to random R level but the prize is a N wild card. When was this changed? Why doesnt nutaku have patch notes/forums on this.

I was so hyped blowing 1.75m pero on N wild cards to end up being useless.
