I created a map right, and everything’s normal, all my assets are from the content drawer, blah blah blah. However, every time I try to launch a session, it says I have an invalid object, that being a Parent Tree, which is one of those smaller type trees I believe. I deleted every tree that I saw had parent in the name inside the outliner, but that did not work. It is possible this is a bug, or I’m just doing something horribly wrong in my map. Can anyone explain or help?

Both message log and output log^

> @InsanePete in your Output Log (different from message log) in the bottom left of UEFN you should see the same errors after running validation as you do in the message log. [image] Above those red errors you should see log lines pointing to .uasset files. If you copy just the names of the .uasset files (Exclude the .uasset part) and paste them into your outliner you should see which actors are causing the issue. Hope this helps! Thanks.

In your case I’d search for OAO8Y46WTT8Z94RHQ80GIP (don’t copy and paste it from here, copy it from your log). Hope this helps!

Thank you, I figured out the problem. It turns out that the asset that had the problem was the large oak tree, and it had falling leaves on. Once I turned that off it let me launch session. Thanks!
