Ok, I've just made the first test... no actived mod, no plugins activated. just the master file and Start Me Up mod. I was on my way to Boston Airport and crossed w/ Watts Consumer Electronics. I know i've never been in this place before. i didn't recognize the name (so i can't say if this can happen in my save or not. but i'll test it anyway). I'm talking about this because i've found there was actually no building in place... Just grey-scaled "flashy" bugs everywhere, "sliding" the screen away. Just like what i saw at Boston Aiport... So, i thought this could be the answer we were looking for anyway and was no need to make another trip and in double distance to see the same thing... So, having the answer i'll now go test w/ the Boston FPS fix and i'll let you know soon. ---- i've tested w/ Boston FPS fix - Vanilla and after entering Boston Area, the game CTD... in other words, the "issue's area of effect" had somehow got bigger or it's just another conflict? right now counting 3 places. (Watts Consumer Electronics, Airport and somewhere between Cambrigde and Boston (the place where i just CTD). anyway, i'll now go test w/ the Boston FPS fix AIO... ---- yes, CTD around East Boston and Boston Airport. Well, no luck at all. :'( A re-install wouldn't make it happen?
