(Xbox) Unloading Unused Assets

So, I've played on PC a bunch, playing on Xbox with some friends. On PC you used to have a couple days to pick up stuff off the ground, it would stay indefinitely if you were close by, it seems on XBox it unloads stuff after the first night. Had a troll knocking down a ton of trees, and mining some copper for me, wasn't to far from my base, went over there and it all disappeared. Is it supposed to disappear that quick to save memory on console, or was that a bug?
