Game Mechanics: Falling Damage Change with New Patch?

[Handull]

did this last patch change falling damage calculations at all? i have jumped from island 4 to island 2 in sky at least 20 times on my monk, and always survived, taking maybe a few hundred damage. the island 4 to 2 jump would inflict maybe 100 damage (i could check my logs for hard numbers). i just tonight jumped 4 to 3 and took 316 dmg. Might be a bit high, but I didn't think anything of it. Then i jumped from 4 to 2 and i took 20000 non-melee damage followed by 32000 pain and suffering damage. My monk is level 54 with max Safe Fall skill. Was I just insanely lucky the last 20+ times i've jumped, or was something patched without being mentioned in the patch notes? Thanks.

edit: ambrotos indicated that it happens from time to time. next time i'm up in sky i'll get a cleric on 2 and play around with what works and what doesn't i guess. might also play around with changing my weight
