I'm sure the AI has some legitimate reason to use refute in that situation, like needing the unit to move after the next unit so they can hit the enemy when its their turn. Not sure if this is the case, but this has happened in 1.39c, so it's not anything new. We didn't change anything about refute.
Were there any other circumstances to this refute, like MP Regen?
