saving game worlds

If you use the original grid small map, add cars and others objects, how can I save that world so I can open it again without re-spawning everything in. I’ve tried using the editor and saving level, And I’ve tried selecting each item in editor and ticking the ‘canSave’ option but it still doesn’t save.

is there a way to do this or am i not able to save worlds

there isn't a game bug or issue that is affecting me, im just looking to find out whether i can spawn props like the barriers or car crusher in the small grid world and save that world so i dont need to spawn everything again each time

thanks for the response

 

ok, thanks alot for the reply
