PC version 1.20 current patch level but prob also in other platforms.
ChenarusPlus Map grid ref approx 2599/2070 (lower section of cliff/rocks below Ostrog lighthouse, well I think Its a lighthouse, never been there as an aggro clan camps there). The rocks have an indent (hole) in them, sufficient for a player to easily or accidently walk into, once in the indentation - the player cannot get out, by jumping, crouching or crawling. Only option is suicide. All I can say is thank heavens I was a relatively new spawn :). Threw all my gear out, (still did not allow me out) then suicided. Dayz was kind enough to give me a relatively close spawn point on second try, (well run like hell on one pear, be red blinking but alive, and recovered my booty). Just seriously lucky, but not really the point.
Dayz has plenty of challenges to fight against, without a hole that you can't get out of :) It's not a fault in the mesh, the hole is solid with no tearing and performs its job as a spider trap perfectly!
