Subject: [PATCH] gameobject: a nameless or modelless object says so, for the
 hardcore graves
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

"note that they are not corpses but actual grave stones from hardcore deaths,
custom twow stuff" — so the corpse plate was never the path, and the three
corpse legs added last commit cannot see this at all. A hardcore gravestone is
one of the server's own GameObjects, which reaches a plate through
`go_inputs.templates` and a mesh pick, not through `CORPSE_FIELD_OWNER`.

Two lines, one per failure shape, each said once:

  - a display id that names no model (`entities::display`, built once per id and
    cached). This is the quiet one: a GameObject with no model draws nothing
    *and* cannot be hovered, because the pick set is built from its mesh parts —
    so a custom display whose `GameObjectDisplayInfo` row this chain's DBC does
    not carry has no tooltip for exactly the reason it has no art.
  - a hovered object with no template yet (`ui_tooltip`), the plate's only
    silent exit. A line with no sequel means the
    `SMSG_GAMEOBJECT_QUERY_RESPONSE` never came, and a server's own entry is
    where that is most likely.

Neither line on the next grave he walks past would mean the object is picked and
named, and the fault is in the plate itself rather than upstream of it.
