Parkour range is reduced with the new Inertia system.
This now causes health damaged when trying to jump over railings onto ledges that never used to result in any damage other than shock.
This might be an issue on Namalsk, prior you can jump silos in Lubjansk but now you MAY not make the jump and fall in between.
In the video provided below, jumping over the rail onto the stairs used to not cause any health damage.
