If I have M4-78 installed I personally like the option to fight Vash in the Enclave. Sadly that's not possible with the Extended Enclave patch. Would there be a possibility to add an option like the original Extended Enclave did? (Or am I the only one who does weird stuff like that? :D)
Also I think I found a bug. If the player kills the 3 Jedi Masters and goes into the Enclave alone, the cutscene with Kreia starts where she sits down, then she says "The years have not been kind to us both, it seems.", then the screen goes black and nothing happens.
I looked it up in DLGEditor and the Dialogue ends there:
In Extended Enclave it continues and starts "a_jediarrive":
