Could mobs see through hide/sneak in classic?

[Treats]

Bump on this I guess. From the Sony board:

I noticed something strange this weekened. I have leveled a couple characters through Dreadlands, so I know that all Drolvargs can see invis. However, when my Rogue graduated to there, I found that they do not see Hide. Certain Drolvargs inside KC, namely the ones up in the "lookout" positions, can see me, but the others can't. I am not standing behind them.

What is up with this? My theory is that in addition to certain mobs being marked "See Invis", certain mob *types* can see invis, as well. Such as Undead, Drolvarg, and certain Gnolls. Sneak/Hide does not hide you from mobs flagged "See Invis" (Shroud of Stealth does, in general)... but it *does* hide you from mobs that see invis due to their "type".

Is that how it works? Or am I just remembering things incorrectly?

I assume he is referring to the Drolvarg Guardians in the lookout positions?

Others can't (Sentry's)

If it is flagged due to NPC type it will see through See Invis but not Hide? (See Invisible)

If it is marked as See Invis will see through both invisible and hide/sneak? (See Hide)

Examples:

Sol B Bats -- Use Sonar for detection
Mob type Sees invisible and also flagged to See Invisible (Sees Sneak/Hide)

Drolvarg Sentry -- Mob type will See Invisible but Unflagged to See Invisible (Doesn't See Hide/Sneak)
Drolvarg Guardian -- Mob type will See Invisible and also flagged to See Invisible (Sees Hide/Sneak)

Random See Invisible Sebilite Juggernaut -- Mob type does not See Invisible
Flagged in Database to See Invis so will see Invisible and Hide/Sneak??

How certain Mobs were set to See Invisible (But Not See Invisible by body type)?
Possibly just a random low percentage chance? No idea.

Hope this kinda makes sense. Thoughts?
