I don't know if this is a bug or is supposed to be like this, but:
1. Interruption of the battle.
If you press "pick up" a scorpion from afar, when you approach it, even if it starts attacking you, you put it in your backpack. The fight ends.
2. Many in one place.
In some places, there are large clusters of scorpions in one spot. I noticed this on the "cursed orange sand" and in small, narrow patches of thickets (or dark forest).
