A problem with fall damage!

All the time fall damage script was working, but not it has glitched somehow. In this .blend take a look at fallDamage.py. For some reason, it doesn’t get the Linear Velocity in property LinV anymore.

OK! I found the reason in fallDamage.py line 24. Actually, I had also wrongly replaced line with get lin vel, but that’s not matter anymore…
