Heres a list of state IDs changed or added by this mod. Note that when vanilla HOI4 adds states, I move my oldest ones to the end (as seen with the Isle of Man, the first state I created), or to fill the gaps of states I already had (Bornholm moved to where I had Cambodia when that state was added in hoi4 v1.2)
