I am currently reproducing this bug on 4.6.1
I am making, directly in Event Graph of widget, a select on enum some textures that go into a Set Brush from Texture that basically sets graphics for an Image within said widget. Enum is defined inside umap, not in C++.
This is a C++ project I am running locally, I don’t know of this is causing problem, but I am reproducing it exactly like in link above. Nothing I did managed to NOT reproduce it. refreshing nodes restores select node, but selected things are no longer set for options.
Its not a error of view, when I compile, nothing is set. node is actually broken.
