Today I wanted to launch up New Vegas and I got a message "this save relies on content that is no longer present"
Previously I had an "update.esp" available in the launcher. Now it's gone.
The integrity check says the game cache is flawless (so this "update.esp" should not be there).
But what's in that file? Is that some pre-order award as suggested by fellow posters or did it contain essential stuff that would be required for me to play?
I have never downloaded anything manually, relied entirely on the Steam client.
Currently, I have only these two files in the launcher (both checked, as always, except update.esp is no longer there):
FalloutNV.esm
FalloutNV_lang.esp
The update.esp is gone.
