The first stage of the tournament "named after Van Kanigem"

After the tournament, I will explain again (for the third time) that this is indeed a bug in Heroes 1! Which, by the way, has been successfully fixed in other installments...
Sincerely, VDV_forever

I don't need you to explain it to me for the third time; I understand what you call a bug and why it was banned.

Here's the situation in Heroes 3. A hero has one action point left, attacks, and retreats. On the same day, the player buys a new hero but cannot move him because the hero's action points are depleted. Everything is normal.
The same situation in Heroes 1. The player buys a new hero on the same day and can move him for a full turn. You say this is a bug and ban it. Okay.
Situation in Heroes 3. The hero has a full turn. He spends one action point, attacks, and retreats. On the same day, the player buys a new hero and moves him for the remaining action points (minus one). Everything is normal.
The same situation in Heroes 1. The player retreats with a hero who has almost a full turn left. But due to the ban, he cannot use it. How is this different? Instead of one bug, we now have another, as can be seen by comparing it to Heroes 3.

But here's the difference. Everyone knows about the bug that you told everyone about, and if it's not banned, everyone can use it without fear of any checks – everyone is on equal footing and limited only by the money earned in the game.
The ban is more complicated. Here, we rely on honesty, and a check is needed to detect violations of the ban. It's harder to guarantee 100% equal conditions.

If we say that honesty and checks are 100% guaranteed, then why not make it so that players in Heroes 1 simply count the green arrows of the hero who is about to retreat? Then, on the same day, he can move with that hero, but not for a full turn, but for as many action points as he has left. Since there are no doubts about honesty or checks, what's the problem? This way, we completely eliminate the bug, and the retreat and buy-back situation will work exactly as it does in Heroes 3.

I'm not going to break the rules and will play according to the rules set by the tournament organizer. I'm just expressing my personal opinion about this bug and the ban. If I made any mistakes in the examples I provided, please correct me; maybe I misunderstood something?
