I use a BP which generates a few static meshes with the BP function “Add Static Mesh Component” inside the construction script. I save the return value of the blueprint node within a variable to save the ref of this statis mesh.
I spawn inside a other BP the BP explained above and constrain them together. To be able to constrain them I get the static mesh ref inside the construction script with a cast.
On begin play I use this ref to constrain them together. And the object ref gets a copy in the construction script of the other blueprint which spawns the other actors.
The Problem, since UE 5.6 the object refs are still valid but the reference frame of this object gets to 0.0.0 and the constraint is broken.
If I ask on begin play the static mesh ref about the location I get 0,0,0 and on 5.4, 5.5 I get the location instead.
But the static mesh is the blue boxed mesh, so definitely exists and also not on 0,0,0
This is definitely a bug
