Vanishing Trees

So this is not a new issue but is still present. It seems to center around trees. I like to plant them outside in varying sizes and I like to shrink them and place them on the glowing coffee table, which makes a nice planter.
As long as I remain at my base, all is fine. But if I leave and then return, the trees may be ‘gone’. Technically, they are still there. They are just ‘cloaked’. Any other item close enough to them will also vanish. Next time I leave and return, they may reappear…I reported this once but will report it again.
