[Westfall] Wrong NPC Display IDs
Since Westfall was such an early zone created for the game there really isn't many issues with it but these are the few that I have spotted while doing my playthrough.
NPC
Defias Renegade Mage, uses display id 4420 and should maybe use the same display id as the defias casters that were corrected in duskwood? (displayid 263)
.port -11319 1719 36 0

Defias Profiteer, uses display id 4423.
.port -10962 1495 51 0

Below gameobjects have been despawned already, see https://github.com/The-Alpha-Project/alpha-core/issues/414#issuecomment-1233067546
Gameobjects
Sentinel Hill
There are four Peasent Woodpile gameobjects in the lumbermill at Sentinel Hill.
All the Guids and Entries are in the 6 figure digits so should all be despawned.

Klaven's Tower This defias controlled tower isn't present in 0.5.3 and most of the objects related to it have been despawned but there are still some left.
Campfire in the ground, entry: 129206 Guid: 32081 .port -11115 513 33 0
Random barrel of milk, entry 3705 Guid 42733 .port -11122 564 36 0
Defias Renegade Mage
it seems weird that the whole area is already reworked by blizzard and there is still a normal mob with a placeholder
New model

Very close from some we can see here (westfall defias) :

entry is low, so she was spawned in same time as others defias here. I'm not sure we can use 263 defias caster placeholder for this mob.
263 was just a quick suggestion.
Gameobjects have been despawned in https://github.com/The-Alpha-Project/alpha-core/pull/604, correct display_ids for Defias Renegade Mage and Defias Profiteer are still missing.
If anything the Defias Renegade Mage should be display_id 2319:
She does look strikingly similar to the new model screenshot posted above, although she wears shoulderpads while the "new" version doesn't.
Most of the missing human models we had so far have been resolved by old human models, especially with such a low id (450)
Old human models sample

it could be 2319 but im not sure we have any other examples of human missing models using something else than old placeholder
Defias Profiteer still missing.
