Note Both of these parts have the following error:

"The effective box size has been forced positive and is likely to give unexpected collision geometry.
If you absolutely need to use negative scaling you can use the convex MeshCollider."

I came across this bug in my career save and I have narrowed it down in a sandbox game. See the craft file.

Cubic octagonal strut and octagonal strut behave wrong when directly connected to a decoupler (or stack separator; diameter does not matter) The parts need to be on the decoupling side.

When staging / decoupling, the struts stay afloat in mid-air. Tested in a vanilla 1.11.0 Win64 installation with DLCs Breaking Ground and Making History.
In my career save, a rover was connected via octagonal strut to a decoupler and the rest of the landing vessel. When staged, the entire rover was rendered uncontrollable.
