So I used the Soul Trap glitch to summon a permanent Greater Bonewalker, but later on decided it's not worth it to drag around a monster like that. So I killed it in the Ald-Ruhn Mage's Guild hall.

Now its corpse cannot be removed. If I try to do ANYTHING with the console (for example trying to say resurrect) it says:


I can't delete it, I can't move it, I can't revive it. Everything gets that line 1 message. What is this and can I fix it?

You haven't mentioned, but does "disable" not work?

1. You might try http://www.uesp.net/wiki/Tes3Mod:Wrye_Mash (never used it myself).
2. Create a plugin that removes the script from the bonewalker_summon ref, then try to disable. Remove the plugin from your load, and then clean your save (sounds crazy, but it might work).
3. Revert to an earlier save.
