moving a berry bush isn’t all that difficult honestly. the point of choosing your starting location is to help you determine what is closest to you, what is easiest to obtain at the start, and if YOU choose a location where there are NO berry bushes well than you have to put up with the struggle of getting those bushes closer. that’s a choice you made after all. I started my most current map on an island with about 3 berry bushes. not really enough to keep them all happy at all times so I immediately took the task of building a bridge across the water to the main land and had them move another 10 bushes to the island. I now have 30 bushes all nicely put together in a grid for easy access along with a farm. if you haven’t started a farm yet or trained a trapper yet than once again, that’s your own fault for not doing so yet. Hearthlings don’t take food with them because they have limited storage on their person they aren’t programmed to take necessities with them and I’m not sure if they will ever get such programming made for them. right now their logic is “I have a task to do and the tools I already have are good enough, I’ll stop the task when I get hungry - go eat - and return to the job after” they aren’t the most intelligent because they aren’t supposed to be super smart.
