Hello,
i am working with structure and it seem that structure sometime disconnect or create orphan pin everytime i add a variable in my structure.
this is working before adding a variable in my structure
and after adding variable:
this isnt working after i add a variable in my structure, this give me many orphan pin, i have to refresh all my nodes by hand… wasting hours to check all the orphan pin and to search for disconnected pin 
everytime i tried to work with structure in every version it never work as intended and structure break everywhere, data are resets, pin disconnect, … we cant work with structure in blueprint because we have to fix all thoses errors by hand everytime we modify a structure…
maybe i should give up on using structure, and try to hold data in a object class ? bad idea?
