Static Meshes, foliage, dissappearing after being packaged

I’m also having this problem. Though re-importing the static mesh does fix it. I was able to dive a little deeper and make the problem come back after I fixed it.

I found if you change the import transforms such as add a -90 degree rotation and change in the uniform scale such as 0.8 and then re-import the asset to take the change. It will break on again on packaging. Hope that helps in figuring out this bug.
