Look: the map is a square, you need the right side. Somewhere near the wall, there's a mentor hidden. Regarding the tasks, I'll be exploring new ones. My editor is sometimes temperamental; it crashes or doesn't launch due to simple things. For example, when I set the goal in the first mission to cross the region (as per the manual), it didn't launch. And yes, I tried to do something different from "kill everyone," and that's how the editor reacted. Kill just one... It's as if demons have possessed it, or I don't understand something about map creation.
P.S. The third map is the most appealing and playable... maybe forget about the Campaigns; you create good landscapes, and your scenarios aren't boring. It's better to have one excellent scenario with a map than an unconvincing campaign. This third map in the campaign is quite good and could be used as a separate scenario! (with minor adjustments)
)...that's why I missed the mentor (or rather, not because of that, but because of the quick victory "over everyone"). And it's not a big deal...you can adjust the victory condition to Kill 'Em All.
