nope, if it bugs out, you'll see the souls in eddies mouth and thats it. no error, no nothing. you can go back and try again - it will stay the same and you loose 1 soul every single time you try regardles of how many souls you tried to put in.
but it seems that you get some or maybe all (i don't know and i don't care anymore) after a reset
i also had some sacro errors, this is a different one
