Invisible Assets when Duplicating

[Chrisdashezz]

As per the picture, ctrl+D (or ctrl+C then ctrl+v) will copy the specified assets but some assets will be invisible.
You would have to delete what was copied and keep trying until it stops creating invisible copies.

This frequently happens in Oman (River bundle is included)

The assets still have collision but are just invisible.

It's a known issue, sometimes happens, just duplicate again until it shows up, then remove the invisible one.
