Hello, I've been playing on the island official PVE for quite some months now and I noticed no alpha rexes spawn at all. Players also report not having seen any since.... forever.
At the moment, me and a few players on the server are killing bosses, and alpha rex fang is required to do beta/alpha tek cave.
I know alpha rexes are not a common thing, but I have well over 3k hours on "regular ark" and they weren't this rare.
Is this a common thing on prim+, or is it a glitch?
EDIT: We've seen several skeleton alpha rexes on the halloween event, but they didn't drop fangs.
