ALL CREDITS GOES TO ksolberg, the original creator of the same 1.32 mod.
If the author update the mod, I will gladly put down the mod.

What's the purpose?
To quote the original description:

I hated that a couple steps or even a 6 inch drop-off would often cause Geralt to fall and roll head over heels.  That just made him look silly!  Even the drowners were laughing.

So here's a small tweak that fixes the worst of that.  Now instead of rolling down the stairs, Geralt will do a quick little stutter step and keep on moving.  

Furthermore, CD Projekt Red introduced new fix in the free Next Gen update that prevent Geralt to roll down when walking on stair, as well as tweak the fall damage.
But they only fix when walking, not when running. Simply because it's... realistic to fall if we run down (it may even kill you in real life).

So this mod has been updated to the new Next Gen scripts, while keeping the little tweak of the original mod.
Now the mod becomes "Gameplay Changes" rather than "Bug Fix" mod.

4.04 Next-Gen compatible!
