I was in ST the other day as a PLD fighting the second boss, and I ran to the spawn point for the clockwork squire. The second he spawned, I lobbed and comboed over and over trying to keep him where he started, which is where you want him. He ran a bit, turned around, and started hitting me. Great! Then, while I was still doing combo after combo, his aggro icon suddenly turned yellow, his target switched to a SMN in another alliance on the other side of the map, and he ran away from me. I provoked, it did nothing. I ran after him, and I could not get him to stop hitting the SMN no matter what I did. As a result, we wiped, and I felt like a total newb. The SMN, btw, was well out of targetting range for me, so I don't think he could have been even attacking the Squire, and I don't see how he could have DoTed it since he was never in range until the aggro shift.

I still have no idea what happened there. Has anyone experienced anything like that?
