More likely it has something to do with the version. Everything I say is for 0.50

Actually slob, the bone trick doesn't work for jackals and wolves, just puppies and blink dogs (any other canines?).

The dungeon shopkeeper and his guards are neutral. Townsfolk are friendly. Until you provoke them, anyway...

If it's easier to grant it to mods than to a single user, do so. I won't touch it anyway :/

Then you're never going to believe the tales of the Heroes Fatty & Slob

No. As you know, zombies are spawned with random limbs and/or head. The same thing happens when you polymorph into a zombie. You may or may not have all your limbs or head. So it makes no difference if you have a head or not as a zombie, when you change back you'll be back the way you were before you polymorphed.

As for zombies reattaching limbs/heads, they can do that with any limbs/heads. I once filled the library with zombies, and when I came back one had the head of the librarian

Ack, I thought I left one out. Thanks Apple

Cerumen, that's all too true, but I meant once it dies

Brown, black, grizzly and polar. Polar bears are the strongest, and the one in Attnam makes for a good pet/food source when you're heading into GC/UT4

You're not stuck as a zombie, and you don't retain the marble head.

Aside from the afore mentioned and overlooked bug, the only way to survive the loss of your head is if you're a zombie. Upon which it is entirely possible to get a head of an unconventional material. I have gotten a marble head once.
