Twintania and strange aggro behavior

[High_Timesw]

Forgive me if this has been posted somewhere, but I did a search and didn't find anything relevant.
My group was doing Turn 5 last night, and for some reason, when the tank pulled twin and her adds, the adds would all instantly aggro our bard. He had no song up, and he performed no actions. The 3 adds simply ignored the tank and went straight for the bard.
Anyone else seen this, and possibly know of a fix? I've seen a lot of posts on other websites, but nothing on the official forums. If it's actually an issue, I'll move this to the bug section.

I tackled this in my Strategy!

The Hygeia do not care what you say or do! They attack who ever they want! Our party runs down together to the left (and runs past the mobs) while tanks go to the right. This way, who ever they pick, it won't matter everyone is close to the OT and he gets aggro on them.

This happens to our SMN just about every pull. and he does nothing at all.
