Current questions and answers regarding the map editor.

The problem is that the creature named limon3 stands with its arms outstretched.

Not all creatures have animations defined in their properties (Shared->AnimSet). The simplest solution is to replace the problematic monster with another one.

And also, a script so that creatures on the map start fighting from the beginning, but when you enter a region, a battle starts with one creature from the pair that is fighting. And as soon as the battle is won, the creature immediately wants to join. Does anyone know how to implement this?

What specifically is causing difficulties? You write animations in the script, place a region trigger, in it, use StartCombat(), and in the battle callback (one of the parameters of the StartCombat function), check if the battle was won and force the hero to click on the monster that is pre-configured to join.
