I love the randomess of the events that happen, but I wanted to warn you that you messed up the normals on the goblins and sometimes their body don't disappear, leading to a softlock :(
To fix this, go into blender, select the model and do "Shift+N" to recalculate the normals.
Don't know how to fix the body not disappearing, but it was fun until I got softlocked.
