.npc set sheath/.ph for npc set sheath behave unreliable

[SunkenCastles 1]

Attempting to use the commands .phase forge set sheath or .npc set sheath produces inconsistent results upon server restart. Have tried using forged vs non-forged items, and the Always Unsheathe unauras to no avail.

Upon investigation, using either commands again to "reset" the sheath state seems to fix it temporarily, i.e. using

.npc set sheath 0

and then

.npc set sheath 1

immediately after. But a server restart will mess it up again.
