Disappearing placeables/building pieces and more

Problem: Bug | Misc]
Region: [NA]

I have a treehouse base (totally awesome, BTW!) and I’m having trouble with pieces of my platforms disappearing when I log out. I will have them all placed and the way I want them, and the next time I log in half of them have vanished. I’ve fixed them 3x now and there is nothing in the logs to explain it. Also, I’ve been having placeables like bowls, cups, etc disappear after placing them in the treehouse as well. Couple clan mates have had their wheels of pain disappear after using them for 3 days straight…again, nothing in the logs to suggest an attack and the building dmg was turned off at that time. Disappearing fish traps as well.
