Hounds Tooth Losing Taunt

Based on your description his vader could have used his special and you just didn't see it. "I have you now" or something like that.

Would still help to know who is on your team.

More info please. What other ships were there? Is there a Falcon attack involved?

How did it happen and who was on both teams? His Biggs and HT or yours?

No falcon their starting lineup as HT, Vader and TIE, I took out TIE they called in Biggs and Taunt was gone. It almost appears if target lock is removing the Taunt.

You'll probably have to give more info on what your opposing teams squad was made up of. There are a few ways HT can lose taunt early. Your ht breach may not stick or get cleansed and hans falcon, tie advanced, umbaran and a couple others can then dispell your ht taunt. Keeping your taunt up all depends on having breach on one of the opposing ships.

I just ran a fight with HT Falcon Cassian on my side, HT and Bistan on theirs, and they brought in Biggs. No loss of taunt.

My team is Vader, HT, Ghost, The dispel of taunt happens before I can bring in Phantom. It is just weird have had it happen 3 times now but as soon as it happens the opposition jumps on my vader and ghost and kills them quick.

I'm guessing its Vaders special.

OK this time No Vader in sight and Houndstooth 2nd attack stripped my houndstooth of all buffs .

If its Milf, then she can strip the 'breach' if the breaches ship gets 3 or more debuts, then the taunt is vulnerable.
If it was Vader, he can strip the taunt if HT is target locked.
If Cassian is in the opposing team, he can strip buffs.
.... I'm sure there are other rebuff mechanics that I don't understand, like with Carth's ship & The First Order shuttle thingy (not KRU's, the other one).
Who were u facing in the second battle?
