Ok listing the "light" issues first
Cloaking does not work
Painting them does not work (not sure if that was intended or not though? )

Medium Issue
They spawn in packs and thus swamping the area they spawn in (ive seen up to 10 in the same place)

And now the severe issue!
These buggers glitch through walls!
They get through even the walls from MRRadTools mod, i have never under my 4200hrs+ ARKing seen anything get through them walls in that mod, well unless it was flying ofc.

Modell of the animal looked awesome though.
