Maybe this was addressed somewhere, but so far I haven't been able to find anything about it- granted, I'm not great at searching stuff sometimes but well.
So, I was wondering; do the kills in dlc maps and my castle battles even count for the statue upgrades? I'm starting to think that they don't, as I have recruited Kana first and Shiro last, have definitely used Kana more often (at least, I thought so) but still no Kana statue; Midori, Shiro and Caeldori already have a statue. Now I have mostly been playing my castle battles and some dlc lately so I'm thinking that's probably it, but I am not entirely sure about the dlc. (so far I've been too lazy to actually start counting kills, maybe I'm overestimating Kana)
Another thing I've noticed is that profiteer never kicks in (on Midori or Azura) in my castle battles. Is that a stupid (and percentage-wise sort of impossible) coincidence, or can someone confirm my suspicion? I've tried using them a few times, nothing. In a normal battle it triggers almost every turn for Midori at least.
