Blueprint error: "Attempt to access missing property"

So I was using a property from a c++ class wich was the controller vertical angle in order to rotate the player’s spine. Via blueprint I accessed to that variable and all was working fine. Problem is when in the c++ constructor I set up the skeletalmesh variable bAbsoluteRotation to true, the player stopts rotation its spine and the editor drops the error message of the title. The attribute that causes the error is the angle mentionet before.
Thanks in advance.
