Found Disallowed object error after update

I loaded up my map after an update and found several of my rock formation missing in the level. After further investigation i noticed this in the error logs.

Even after “fixing” the errors they did not come back.

I find it odd since these assets are default assets from the game is there a reason why they would be disallowed after an update. Also they are still available to place from the content browser so im super confused.

lost a bunch of work on my new map and would like to know what went wrong.
