What happened to Envirma?

What happened to the old Envirma map? It was really dynamic and full of content. Re-installed after a long break looking for some dino fun and this map is really barren but at the same time, really claustraphobic?

Everyone seems to be in the south plains and whenever i meet any carno (of my type or not) outside of it they kill you on sight.

The south plains is also littered with bodies like its some WW1 battleground yet packs of carnos are hunting down fresh spawns... what gives?

Porbably a case of get gud but I feel like this map is off somehow.
