samme issue for me

logging in, instant death at random location (where i havent been before what i know) and are greated with "you died" (from falldamage)

Same problem for me. 

Was online outside base at villagercamp, answered some emails, came back (lost connection/kicked whatnot) 
exited, connected again, and was teleported somewhere completely different, and instant death "from falling" (with featherfalling IV equiped)

this happened another time aswell, this time after saving and exiting, and at my base, middle of dessert, inside, also teleported to another place completely, welcomed by "you died" messege.  far away. (have searched for equipment far around with no luck)

Error seems to be random. 
Will quit playing untill fixed.
