[Mod request] Bypass save lock for mission "(Don't Fear) The Reaper"

[Absovec]

I know why this lock is present, plot reasons and all stuff, but game is damn buggy, and in this mission game bugs the hell out, all possible bugs happen for me (impossibly slow reloads, no sounds, no animations, actors stuck in walls and others), and the only way i know is to reload save file, but game doesn't even create save in the beginning!

Because of what i have to sit again on the roof for the five minutes.

Plus i want to try different endings.
