Each of us talks about our own experience - I talk about mine. I never have time to get the shells from the very edge of the map on the left. Also, I was only able to carry a shell from the top of the mountain once.
But personally, I solve this more simply: I don’t kill shells where it’s risky, or I just kill them so that mobs don’t accumulate. And I don’t even try to carry the shell to the refrigerator)
But I believe that this annoys some people and we can try to change it. That's why I wrote my post in support of other people.
Sorry, I don't know English well and I'm using a translator. Therefore, my posts may look strange.
