Just started playing, and I am seeing kinda like brown shadows of old sprites in male viking(lancer), and female sentinel(knight).
Also I extent the ISO.
Well I invited the first brigade that I saw, and she didn't have sentinel level 3?, but had sniper job unlocked and stuff.
Also when werewolfs die, they are still standing after.
Edit: more to that Invited thing, it's not only invited, it's every single one of new units that you get(not counting guests).
