Like a lot of others I've had trouble with the infinite movement. I believe the issue is that if you're like me and impatient and/or want to change the direction your troops are going while they're on the move, you "reset" the move counter to what it's currently on when you alter their course so that they only have half or a third or a quarter of their max move when they finally arrive at their destination. This goes for both armies and heroes, on land or at sea.
The God Mode also does not work, or I'm using it wrong. Autocompleting battles awards me lost troops and battles. I have yet to try God Mode while in battle mode though.
The rest is fine so far, for High Elves and Dark Elves at least. Gonna try out Skaven next.
Also I've not used inf. magic, inf. ammo, add EXP or Set Skill Points so I cant speak for them.
