Maybe, but I had to edit the the CoreUnits file to get it to three, and I did that just after posting. And as that does not affect the game in progress I haven't run in to him since.
Edit: I found 2 CoreUnits files,
C:\Program Files (x86)\Steam\steamapps\common\FE Legendary Heroes\data\English edited 05/20/2013 This one has movement 3 2.133 kb
C:\Users\xxxxx\Documents\My Games\LegendaryHeroes\Units edited 06/24/2013 -> the one I used to edit the 1 movement to a 3 2.156kb
I don't know how thats possible, the things I'm sure of are
1) he had 1 movement in my game
2) I edited him in a CoreUnits file from 1 to 3
3) I have those 2 files with those dates.
