Asura no worky on Tatacho?

[Naruhodo]

So I was asuraing the new world monster tatacho just fine a few hours ago... but when I logged in now my asura always does 1 damage to them and doesnt take my sp away, and it doesn't do that for any other mob... very weird. I looked up Tatacho's skills on RMS and none of them should be able to make asura act wierd like that...

(I know, RMS is not the most accurate source, but doing @mi tatacho and asking on @main didn't provide any answers either)

And yes, I'm sure that these tatacho weren't the mvp's summons...

So I made a ticket about it, but in the meantime, anyone have any theories? I'm counting on the great detectives of the heRO forums to help me out
