On official server 2602 | EUROPE - DE (Livonia) I climbed onto a long brick wall with concrete caps and walked along the top of it. Where the wall meets a building, the character dropped off the wall and, instead of landing on the ground, fell through the terrain and ended up under the map (white void, with the terrain, trees and buildings rendered upside-down above). The character fell for several seconds, landed on a surface under the map and took damage (blood indicators on screen, injury icons in the HUD). I selected Exit; during the 15 s logout countdown the screen faded to black. When reconnecting to the same server, the loading screen showed "Timer prolonged due to waiting for the end of previous session." Video and screenshots attached.

1. Join official server 2602 | EUROPE - DE (Livonia).

2. Go to the long brick wall with concrete caps next to an overgrown lot with wooden pallets and a two-story dark wooden building (see screenshot 01_wall_location).

3. Climb onto the wall and walk along the top of it to the end where it meets a building.

4. Drop off the wall at that end.

5. Result: the character falls through the terrain and ends up under the map.

The character lands on the ground next to the wall and does not fall through the terrain.
