Hi, I am running into a similar challenge.
I installed the Premium 2.0 Plugin and am trying to include the Scene in a custom menu with some VisuStella Core elements as well as the MK_UI Customizer. I can Call Factions from an event just fine, but the Scene Call via the Menu gives me a "not defined" error / Script: SceneManager.push(Scene_WDFactions_Pr);
I moved the Plugins around to no avail. I can circumvent the error by triggering a common event with the Call Faction plugin, but exiting the view exits the entire menu and that's not ideal.
Thank you!
