Hello. I added the Static Mesh Component and the Physics Constraint Component using the Blueprint. I started the game in the editor, everything works as intended. But in the log are written warnings "attempting to create a joint between objects that are both static. No joint created. " How to fix this? What does “static” mean?  
In advance thanks for the answer.
