Some bugs I've noticed when using the 'Move All' button:
1) While the move all is in progress if any pop-up menu gets displayed (any bless, any battle etc) the move all sequence quits and doesn't finish moving all the rest of the armies once the pop-up menu is canceled. This means the player must hit Move All repeatedly if any pop-up occurs. Can the sequence auto-resume when pop-up menu gets removed (this can mean multiple menus if a battle leads to the city capture screen and the hero level up all in a row)?
2) While the move all is in progress any fog of war armies uncovered doesn't seem to stop the army move sequence for that stack as it does in normal movement. At least it didn't appear to do so for me. It should stop the move just as it does for a normal move.
3) This one is not related to Move All but now affects it in an important way. If you are out of moves in a stack and you plot a new move sequence the sequence is shown. But on the next turn the Move All won't move the armies. That's because the movement path is lost because the game isn't saving paths that have not started yet (this has been reported many times before). It's important to be able to plot new sequences for armies that are out of moves so that on the next turn the Move All will move the units.
