Why is this actor falling through the floor?

It happens about half the time, even when i make no changes. All I’m doing in the video is starting and stopping the game. The last 3 attempts show it behaving normally.

Edit: the other items have the same parent item, but this issue doesn’t happen to them. I’ve tried raising the item so the sphere is not overlapping with anything and the issue persists.

If you enable physics on a component of an actor, it will fall regardless of whether you have a collision sphere or not.

You might get some joy from enabling CCD on the component ( continuos collision detection ).

The collision sphere is only there for an eventoverlap with player; I just thought I would mention it in case someone was like “lift it higher,” but I didn’t think it was involved in my problem.
I ended up just rotating the item a small amount in the Z axis and that seems to have made it more consistent.
I was just confused as to why it was clipping through the floor at all and only some of the time.
