I have this issue where sometimes auto face target doesnt always work. Like...

Titan double gaols.
I stand behind him and dps down the first gaol as blm.
I get pushed back by upheaval but I'm already targetting the second gaol.
I dont get targetted by landslide so I just start casting.
Cast bar starts and then gets interrupted soon after because I'm not facing the gaol.

So apparently titan's upheaval locks my facing direction from auto facing even after upheaval has already finished?
