Go to the config menu, then cycle the midi output device until it says "No output device".

Whoops, I think I forgot to compile with wizard mode enabled. I'll update the binary.

IVAN 0.507 is out!

Sorry for the delay, I was sick this weekend.

There's this out: https://github.com/Attnam/ivan/pull/175
In the data files, humanoid ghosts (spirit) already have

BodyPartsDisappearWhenSevered = true;

so it should work like golems and genies now.

I'll make ghost limbs severable, and make them disappear when severed until I can think of a proper way to do this.

The reason I made it so ghosts couldn't lose limbs is because it seemed odd to hack limbs off a ghost. Head, torso and groin are still vital on a ghost.

There are a number of possibilties:
1) Make ghost's limbs disappear when severed - most common behaviour for a few special humanoid characters
2) Make all of the ghost body parts vital - easier to one-hit a ghost
3) Redirect all the damage incurred on arms and legs etc to the torso - easier to land blows and probably kill the ghost faster
4) Leave it as it is, JoKe's WM-pumped character wasn't landing any body blows anyway.

Does it need to be fixed? Or is it a new and curious feature?

You could say it negatively affects the game.

Menu, victory and defeat tracks are actually empty at this stage... but that is a good point. I don't know how the music would respond.

Um, so to simplify matters we reverted the change: https://github.com/Attnam/ivan/pull/171
This means there will be no change in the next release.

Update: The lead dev (Adrian Gin) for the music subsystem published a guide on the wiki outlining the allocation of channels inside each track: https://attnam.com/wiki/Music_Creation in case anyone was keen to write tracks for the game
