So i've used this before for fe4 and I love it, but now when I am trying to do another run it gives me all the same classes and growths from like a pool of pre set stuff? Sigurd keeps being the same classes with the same blood and growths to a t as previous randomizations. Was just wondering if they pulled all the changes from a pool or if there's some way to fix this and make it more random. Thanks!
