IsPOIPublicDungeon

[circonian]

Am I missunderstanding what IsPOIPublicDungeon(..) is supposed to do?
The rest of the IsPOIxxxx functions do what their names suggest, but either this one is bugged or it just does not do what its name suggests.

I've tested IsPOIPublicDungeon(..) on every public dungeon in every zone I have access to, they all have the words public dungeon in the icon path name, and I even reset the tutorials and entered one to verify that the game considers it a public dungeon:


But using:

IsPOIPublicDungeon(zoneIndex, poiIndex)

Returns false on every one I try it on.

EDIT: I even tried testing every POI in every zone by doing:

for zoneIndex=1, 1000 do
    local numPOIs = GetNumPOIs(zoneIndex)
    for poiIndex=1, numPOIs do
        if IsPOIPublicDungeon(zoneIndex, poiIndex) then
            d("Public Dungeon Found: "..zoneIndex..", "..poiIndex)
        end
    end
end

and the only POIs it returns as public dungeons are in Craglorn.
