This seems to be related to the video posted yesterday of the guy jumping from the bottom of point B devastation conquest over the barricaded glass doors. But landed on the 2nd floor where the mcom would be in rush.
Or the guy reviving through a wall.
Game just "loses" you for a second and by the time it catches up, it doesn't know you've passed a hard object. Waiting for people to use this to get OOB but still in the game, I mean it has to be possible if this is possible.
In the case of vaulting it makes sense since physics is getting bypassed for a while, but in this case there shouldn't be a valid reason for the physics body to go through the terrain. No matter the angle or velocity, physics won't let you pass unless something else goes wrong, so the question is: which system is responsible in this case.
