[LVL ED] Level editor won't set a sound entity to a sound element

[TheGreatCthulhu]

If you try to add the snt files from the game itself, does it work?

I am not sure what you mean - from Amnesia? Well, I did not know I could do that, and don't see how.

No, no, I meant, if you were using your own snt files, does the editor load the sound assets that came with the game - but those are the ones you're using.

Maybe the operating system denies write privileges for the installation folder to the editor app? Can you right-click, then run as admin (not sure if it will work)? Has this sort of thing happen before? If you save the map to, say, desktop (for error testing purposes only), does the sound SoundEntityFile attribute remain set?
