I think I've actually either stumbled upon a bug or something else entirely. So, you have 5 sections on any character, right? From left to right on the talent menu. For some reason, if you build another card on the same section, (or line, whatever you wanna call it) it completely negates the card underneath. I noticed this today actually with Aneska. I was trying to see how her Survival card would match up when I used both the Rare and the regular one. (It basically just gives you 90 HP when you use a finisher on an enemy.) However, I noticed that it completely negated the card if I had a card above it. Not sure if this intentional, but it seems kinda weird, seeing as you cant really destroy cards.
Any one of y'all ever gotten this issue?
