It's been posted that WildCard has implemented a new anti-meshing system, A Message from the Founders - ARK News - ARK - Official Community Forums.
There is a section at the bottom about deactivating it for Unofficial Servers,
By default, the anti meshing system will be on for the Official Network For Unofficials, these launch parameters can be used:
-noundermeshchecking // Will turn it off the anti meshing system entirely
-noundermeshkilling // Will turn it off the anti meshing player kills (but still allow teleporting)
How does one use those parameters on a hosted XBOX server?
I ask because there is already a forum section for false positives, Anti-Mesh System False Positives - General Discussion - ARK - Official Community Forums, and we don't want the new system killing us in new and different ways. We're perfectly capable of dying all on our own.
