Tyrannosaurus Lag & Double Bite Bug (Asian Server)

When fighting this Tyrannosaurus on the Asian Server at Stillwater Swamp, my game became extremely laggy. The dino could also perform two quick consecutive bites. I have recorded a video of this issue.

I had no lag at all before engaging the Tyrannosaurus. The lag only started after I began combat with this individual dinosaur.

Tyrannosaurus should follow its normal attack rhythm, and fighting it should not trigger sudden heavy game lag.
