I flew down from 200 block height and landed gently on snow, I died instantly with feather falling 4 boots on, this is the second time I have died to a glitch live on twitch treating it as hardcore, viewers are really disappointed. Link to view clip is below. I tested flying directly into the ground in the same conditions at full speed after and only took 2 hearts of damage, what killed me the first time?
