Shauri's Sonorous Clouding

[Drona]

I'm not sure where to post this but...

In Siren's Grotto there i'm looking at 3 entrance mobs. 2 enthralled molkors and 1 enthralled bulthar.

When i cast invis song (a soft mist surrounds you) and con the mobs they appear indifferent and do not aggro when i'm in range like the normal invis that i'm used to.

But after the song cycles and i get the second message (a soft mist surrounds you) they con threatening ( which is what they con when im not invis ) and aggro as if i'm not invis.

I don't think this is the way either these mobs or this song is supposed to behave. I'm pretty sure it would make sense that either these mobs see invis and should con threatening at all times, or they dont and should not aggro.

Anyway, i'm also not sure wether this has anything to do with the fact that im using the epic as a flute (i dont have a flute to test)

Since ive never run into this issue on p1999 blue, i'm posting it here.

(I also have a video which shows what is in the picture plus me actually being in aggro range and having no aggro when im indifferent then catching aggro when the song cycles... if you need to see it)
