Remove Instance (Foliage) - crash dedicated server

Hey ReduxRus-

Since you already have a possible fix suggested, would you be able to submit that as a Pull Request on GitHub (https://github.com/EpicGames/UnrealEngine/compare?expand=1) ? That is our preferred method for receiving suggested fixes. If you are unable to do so, or prefer not to, let me know and I will get a ticket put in for this issue and mention your suggested fix there.

Cheers
