try to use focus as TotT target...yes I'm using target tricks from the cc and in game the same person on my set focus too.
i mean, click the button "use focus again", that it clears the name in the gui, then it should use your focus target for TotT.
the "get TotT Target"-function could theoretically interrupt the rotation, but only because hb doesn't recognize the player sometimes...
but i don't think thats the problem you have... but you could try that...
