Lukas Matena 76927ce399 REVERT LATER: TEMPORARILY MANGLED reload_scene FUNCTION 
This commit horribly cripples reload_scene function just to update volumes in scene so that Hollowing and SLASupport gizmos can be updated to the new logic
    It should be later reverted and the same be achieved in a better way
