Already had a project everything was working fine. I upgraded Playmaker through asset store overwriting old version then upgraded unity. Now everything still works as it should except the get child function all the gameobjects which I try to store the child in are empty once the state with the function is left.
I tried using get child function with tag or name and both same result. Thanks for any help.
EDIT
Currently to work around the issue I'm using the old get child script searching by tag and it is working fine.
