So this has been going around on the gweth today (I'm not the person in question) :
>> Your mind hears Woten thinking, "{faintly}" "As a PSA for those who missed it before, even permanently bonded and registered weapons can be destroyed if they are lodged into an arisen zombie that dies. RIP sterak axe, you are gone but not forgotten"
Seems to me this is a bug and that anything lodged/held/worn in/by a zombie should just end up on the ground after it dies/decays. I don't see any reason why items should vaporize with the zombie, either from the Necro's standpoint or an aggressor's, and it doesn't seem to me like it'd be that hard of a change to improve everyone's quality of life.
