I´ve got this error when a player try to log in and actually don't know how to fix it.
I already replaced login.lua and 050-function.lua with older files but the error still appears...
Code: 
Player has logged in.
[Error - CreatureScript Interface] 
data/creaturescripts/scripts/login.lua:onLogin
Description: 
data/lib/050-function.lua:204: attempt to call global 'getCreatureCondition' (a nil value)
stack traceback:
data/lib/050-function.lua:204: in function 'isPlayerGhost'
data/creaturescripts/scripts/login.lua:32: in function <data/creaturescripts/scripts/login.lua:6>
