There's a flaw in the Gadukino content, if Sveta agrees to help her grandparents looking for berries and mushrooms during the afternoon. If they ask her for more than 1Kg of either, she has to go deeper into the forest to get the required amount. And if her bushcraft score is low, this means she invariably gets lost, and thus wastes time trying to get her bearings again. This often means she doesn't get back to Gadukino till the evening, when her grandparents have usually gone to bed. Thus making it impossible to complete the task.
Even if she approaches her grandparents the following day, they always scold her for not doing what she agreed to do, even though it wasn't her fault. If anything, it was her grandparent's fault, because they would surely know it wasn't possible to get more than 1Kg of berries or mushrooms, without going deeper into the forest. Why would they ask her to do something, that would be impossible to complete, without ignoring their advice? That doesn't make any sense.
And why when she did attempt to complete the task, does she act like she forgot about it? Later on she sells the mushrooms and berries in the village, so she definitely has them, so why not just hand them to her grandparents then, to prove that she didn't forget? That seems so obvious to me, so I'm asking the question why the person who wrote this scenario didn't consider that?
In any case, there should be somewhere for Sveta to leave the berries and mushrooms, after her grandparents have gone to bed, so the task can be successfully completed. Because at present just putting them in the storeroom at their home doesn't achieve that either.
