way to undo tree removal by accident with paver?

Is there a way to undo the removal of a couple palm trees I did by accident while tinkering with a paver. I wanted the paver near them but did not want to remove the trees? I pulled the pavers back up, but my palm trees are still gone.

 

if you yanked the paver, you probably just need to reload the scene

 

Zoned out a couple times last night thinking the same thing. No good. So went to bed. Logged in this am and my trees are back! Thank you for your reply Ally Oop!
