I have a bug or idk a stupid very bad game mechanic.
I am currently making a Egypt Empire, when I move parts around, they just “fall” down.
I mean they are going to the side where I am dragging them, annoying!
And when I scale parts, for example to the Right, it goes to the Right and left side! ANNOYING.
And if I put a part on another, I can pick it up or move it someone else because a blue Icon is there.
Make sure you anchor all of your parts. Also when moving a part close other parts use the moving tool it’s helpful! I’m not sure why when you drag to the right it goes to the left, and right. That’s weird. I hoped I helped you though! (It could also be Constraints.)
