Just wanted to say that by following this guide, even though neither FlyUS nor Vangellico recovered, I still ended up with 2.1 bn dollars. And in another save in which they failed to recover, and Redwood didn't go up 300%, I still ended up with 1 bn dollars roughly. So this is a great guide even if some elements appear to be random. Even just putting off the Lester missions and doing nothing else will net huge sums.
And this was with only 50 to 100 K per character by the first heist, and Betta maxing out at only about 50%. My characters own every property now including the golf course, which is hugely satisfying because I'm a completionist in games like this and couldn't stand not affording it before lol.
Glad to hear it worked out! Vangellico seems to be the most stubborn. Odd that FlyUS never recovered though.
Well the real problem was that it never crashed to begin with (unlike VAG which did at least decline... though by game's end it still hadn't recovered.) I am working with the theory that every game has a random seed that impacts some of these working. Would also account for why sometimes stocks don't reach the maximums others describe before falling again. Some of it does seem awfully arbitrary, too. In the games I played where Redwood never recovered, it stayed low for the rest of the game, whereas when it did increase it always went to 300% or 299% like clockwork after dying enough times, as if preordained.
I can only speculate that all of this is their way of programming some aspect of randomness into it all so it won't feel quite that transparent (even though it kind of is lol.) Still a cool mechanic though.
