I'm using SilverDragon v90005.1.

I used my Large Storage Fragment to spawn Data Anomaly (Balnazzar). SD correctly detected him on mouseover. However, as soon as I pulled him, SD announced it had detected Data Anomaly (Baron Kazum) based on Balnazzar's yell. Kazum had not been spawned.

Key text:

[09:36:40] Rare seen: Data Anomaly (Balnazzar) (mouseover @ 63.4,57.1)
[09:36:47] Data Anomaly yells: You fools think you can defeat me so easily? Face the true might of the Nathrezim!
[09:36:47] Rare seen: Data Anomaly (Baron Kazum) (chat @ unknown location)

This is essentially the same issue as #123, but isn't amenable to a similar solution. There's legitimately a bunch of rare-flagged mobs in the same zone with the same name. Yells don't expose the ID of the unit that's yelling, so there's no way to tell which is which. (Well, not without just hardcoding the text of the yell, but that becomes a pain with localization.)
