I have a 100%-reproducible crash when I attempt to delete a Timeline object in one of my blueprints. I go to the Blueprint graph, select the timeline (which isn’t connected to anything and has nothing in it except for a couple of tracks), and try to delete it, and I get a crash (see call stack below). This happens regardless of whether I delete the tracks first and regardless of whether I attempt to delete it via the Delete key on the keyboard or by right-clicking and selecting Delete.
