Foliage mode causes invisible 'ghost foliage' that retains collision and is visible in editor when placed under certain conditions

Summary

When placing foliage within the bounds of certain Fortnite props, the foliage becomes invisible in session whilst still being visible in editor and keeping collision in session, the collision jitters almost as if the client side has no collision but the server does.

Steps to Reproduce

Create a foliage mode asset and place it within the bounds of certain Fortnite props. NOTE: not all props work. ‘Rock Common Medium A Disp Moss’ seems to be one of the many props causing the issue so try it with this prop.

Expected Result

The foliage asset stays visible as shown in editor and maintains proper collision.

Observed Result

The asset is visible in editor but not in session, collision in session remains but in a bugged state.

Additional Notes

The fact that this has not been fixed yet despite many tickets with high activity, some of which dating almost 2 years is unacceptable.
