Heroes battle: “Power over the world”

I logged into the game on my first try, and the first annoyance was that hero names could only be entered in Russian (they later announced in the chat that it was fixed). I completed the tutorial without any problems (I built everything and hired everyone), and I noticed that dividing troops for a hero is done using a slider or the "max" button, which, in my opinion, is not very convenient. It would be good to add arrows to adjust the number of troops being moved, and also in other windows where similar actions take place. Loading... Even loading the windows in the Castle constantly freezes (I have to close them and reopen them). Is this a bug or just an oversight in the game engine? Although the map loads quickly, and my internet speed is around 1 Mbps. I also noticed something else. After I killed the artifact guards, my hero returned to the Castle, but the artifact was not with him. Where should I look for it? And the MAIN question for me: after a battle, is the hero always required to return to the Castle (except when he settles in a captured mine)? I captured a gold mine, and there's a level 2 artifact nearby with weak guards. It would be nice to pick it up on the way back and then return to the Castle with peace of mind. But instead, I have to go back again...
