I had this very weird bug. It kind of solved itself but I wanted to share it anyways
I built this tower a while ago and one day I log in to find that one foundation(on the right) is out of sync. Strange as there is nothing underneath that could make it align like that. My attempts at destroying it failed miserably. Every time I selected the foundation and clicked ‘destroy’ it would destroy a foundation elsewhere on the tower. The foundation and wall got destroyed in this screenshot(all the way up to the roof and removing a piece that had support.
I shared the misconduct of this one block on social media and I guess it felt the shame coming so it suddenly went back into place. Just in time as I thought about destroying the tower entirely
So you see, public shaming does work!
