This may well have been commented on before, but given the speed this forum turns I cba to search to see.

The following pictures show what happens when you land a helicopter and get out, picture 1 shows a warp with no consequence, pic 2 & 3 show major problems.

Pic 1: https://www.flickr.com/photos/184316...posted-public/ I got out of the helicopter shown in pic 1 and warped to where Im standing.

Pic 2: https://www.flickr.com/photos/184316...posted-public/ I landed the Heli on a H-Pad shown and warped underground.

Pic 3: https://www.flickr.com/photos/184316...posted-public/ I landed the Heli to loot the truck and warped into the ground.

Also on another occasion, whilst doing a escort mission, I landed the Heli at the drop off point and warped away, i was crouching but the animation looked wrong, when I hit the crouch button my legs sunk into the ground, but when I hit the prone button, I laid down and was able to move away from sinking area, once away I was able to stand and continue.

Also after leaving a flying Heli and parachuting down, when I hit the floor I warp a short distance but havent gotten stuck in the ground yet.
