I was just editing a LTN combinator, and I forgot to close the GUI for the combinator before clicking on Finish. The GUI was kept open in the normal surface without a way to close it. I succed when re-editind the same BP and re-open / close the same combinator.
Didin't tested with other types of GUIs
BTW V, awesome Mod, for this awesome game ! thank's a lot !
