Ark is currently full of players exploiting through the process of meshing. Meshing involves using game items and mechanics to exploit and raid other players. Here's my quick easy fix proposal until the devs can fix it at a deeper level.

HOD MESH FIX PVP PROPOSAL
-get rid of the climbing pick
-get rid of sleeping bags (change mechanic)
-get rid of chair
-make all mesh inside no build zone (center specifically)
-no cryo while player is grabbed
-no player picking on karkinos
-limited building on para
-sleeping bags can't be placed in enemy radius
-no eating narco on pvp/narc grenades
