User description:

However, this other blueprint I've put in the screenshot below does not work, the constraint seems to just break on play, and I really can't see why it would. I'm parenting the constraint node to one of the objects im constraining, and setting world positions etc, but otherwise its pretty much the same as your example right? The only other main difference is im creating 2 box collisions in the construction script, they are not pre existing components in the blueprint.

1. Open the attached test project
2. PIE

Results: The physics constraint will fail to hold one of the cube collisions

Expected: For the physics constraint to hold (it works in Standalone Game)
