Twice I have died from very short falls. The first was dropping over a small ledge on a building, prehaps 2m max, by a staircase. The building was a building under construction in SOUTH BEREZINO.

The second event was considerably stupider, I was walking west after just leaving DEVIL'S CASTLE and i moved over a small boulder in the terrain. I must have dropped less than half a meter and instantly died.

For both events, i was at full health (as far as i know) with no hunger or thirst needs)
