I finally killed it!!.. with a rock… for good!!!
what a nice way to dust of my RAM modules as I rarely have a chance to go full rampage on my 32GB
insta-killed the engine after loading my savegame giving me a steady RAM increase
no reaction from the game (could roam around with the camera but that’s it) after having some major issues
well… time for a new savegame then… 2521 here I come 
(should I modify this thread or start a new one? please advise ^^ )
