NPCs/mobs not aligning to terrain
Current Behaviour
Certain (random) mobs and NPCs will sink into ground while standing or patrolling, resulting in inaccurate alignment with the terrain geometry. On occasion they will completely sink into the ground with only head sticking out, correcting themselves a few seconds later as they move around.
The issue appears to be random, and occurs in every (vanilla) zone i've tested so far. However there are certain places with stationary NPCs where the issues is consistent (such as Org bank NPCs). The issue is widespread across all zones, dungeons and NPCs/mobs, however it's only evident in a handful of instances where the alignment appears to be off.
Expected Blizzlike Behaviour
NPCs and mobs should closely follow the contours of the terrain, without major clipping through the ground.

Steps to reproduce the problem
An example that appears to be consistent:
- Deploy a fresh server with no modules
- Travel to Orgrimmar bank
- Note the positioning of the bank NPCs relative to the floor, as well as the guards inside/outside of the bank.

Probably related to #18200 in combination with incorrect / not sniffed spawns
It does seem to have some relevance to it, however based on my observations the NPCs/mobs in question did not spawn underground or unaligned. They simply traverse through the ground randomly, usually when on an incline or uneven terrain. Normally a minor amount of clipping is expected, however in this case a large portion of the mob ends up underground - sometimes going as far as fully submersing underneath - like in this example during combat:
Please note that the mob in this example was not spawned underground. It was stationary in its regular spawn point at the appropriate z value, prior to combat start.
My apologies if i misinterpreted the linked issue.
