I'm not sure if anyone has posted this but I started noticing it and I wonder if it is a bug because it seems like an issue to me. I am noticing that leader skills after upgrading are going backwards. Maybe the characters are bugged in receiving the best skill first and unupgrading when I actually upgrade? I have no idea. I have proof of just 2 but I started noticing it before I took these screen shots. This is a pretty serious issue for me even if it is just isolated. I have screens from 2 separate characters doing it and will take more in the future once I train them.
