[ТУРНИР - SoD] "SM-masters"

and what will that change?

Essentially, we have a treasure, marked in orange (it might be larger).
There are two paths leading to it, and the terrain type is the same, making it difficult to determine how the guards could have moved (the dwarves were likely moved as mentioned above, but it could also have happened as I showed), so in such situations, there should be a more obvious indication of intrusion into the zone: taking resources from the zone, visiting the object, crossing the 100% boundary of the zone.
If in the case of Timbuktu, we can state with 100% certainty that there was an intrusion into another zone, then in this case, we can only talk about it when crossing the orange line, where the hero stopped (see screenshot). Therefore, personally, I believe that there was no clear violation here, and the hero stopped at the boundary of what is allowed.

PS In addition, there is an interesting point in the rules regarding redraws, which states that if the increase did not affect the outcome of the battle, it is not considered a redraw. Personally, I believe that here too, it is necessary to make an adjustment to the rules and take into account whether the hero could break through this guard without any harm (in controversial situations) and whether this breakthrough/non-breakthrough would have affected the outcome of the game.
