Scale is causing unexpected other scale

[small barn]

I have an instantiated child scene that I am trying to flip via inverting the scale left-to-right. This works fine in the editor, but when I run the game the inverted versions all doubly invert (see images). There are no other code manipulations of scale.

I have also gone into each sub element and made sure scale x/y is unlinked, but it doesn't affect it.

What might be causing this?

Thanks.

I guess it's this as my root object is rigidbody https://github.com/godotengine/godot/issues/89898

Just to confirm, it would be, yes

Rigidbodies do not like being scaled, and will reset their scale on ready I believe

The reason it looks like it flipped twice is because it's actually been changed into a rotation
