Is the rex exceeding max level glitch still a thing on the lost island map?

Is the rex exceeding max level glitch still a thing on the lost island map? only see topics from 1 and 2 years ago but nothing saying it was fixed.

I believe it’s only x rexes that reach lvl 500, haven’t seen any higher than that.

if you look it up the videos seem to be both regular and alpha rexes glitching to these numbers but only in the little square of highlands like area on the lost island map
