Workaround for some hacky environments that mess up things 
2 people had issues where some plugin is doing some reallly insane NMS hackery
that created invalid worlds, which caused some errors...

Really don't understand what in the world they did, but putting in a dumb guard that
shouldn't even be necessary to just not send the sound effect rather than erroring.
