This unfortunately is not the same issue I don’t believe, correct me if I am wrong. I ran into this thread a few times while debugging my issue. These variables are reset during design-time, usually when editor is closed and reopened. Mine is resetting during run-time.
So my issue with the enums seems to have been resolved, but I found another instance of a reference variable being reset to NONE at run-time again today.
it is literally, 1st frame Set VariableReference (has legit value), next frame Get VariableReference (NONE). If I make the value public, it is working fine. I might have to dig into the Saved/Config stuff a little more after all so I can get to the root of this problem. It has been a very frustrating bug.
