BLITZ TOURNAMENT

I planned to leave the original puzzle unchanged, but I felt it wasn't entirely appropriate for the purposes of a blitz, so I added some small touches to the master's canvas, hoping that I wouldn't spoil his work too much... :)

Thereby cutting the Walkthrough down to the end of day 1, although in the original, the map is designed for 2 days.

P.S. And another question (probably off-topic, but nonetheless): Can anyone tell me why the hero-farmer digs heroes so crookedly, i.e., if a hero needs to be dug in the second Castle, after digging a bit (3-4 times), for some reasons (unclear to me) it enters city 1 and stalls there ??? I have to manually enable it again, and so on in a circle. Yesterday it wore out all my nerves, and I still couldn't dig up what I needed ...
