mmmhm, downloaded the CAGE mod, cuz i still want the story to push through rather than loading back to the save point.. now my issue is.. the securitrons are still there.. along with general oliver. and now even if i speak to him. a conversation starts by eliminating the legion in the fort. but after that convo, the hud disappears, but i can move my camera freely and thats it.. no fade out.. .-. is that normal?

Yeah it is, unfortunately.

The game isn't really meant to be played after it ends, bugs are very much present in the mods that allow this.
