I'm playing on the download version, windows 64 bit. I have everything possible unlocked, in 1987, 25 MHz, PLCC240, PGA176.
I was playing normally, and then I got to 1988. No new technologies to research. I thought, "Huh, weird. Maybe this was just a slow year!". I kept playing, just sitting there waiting for the next year. The next year comes, no new tech. I got confused when inlet released a 30 MHz CPU when the current max for me is 25(Note, apparently I should have unlocked 30?), and checked the wiki. Sure enough, I should have unlocked a ton of stuff. Luckily I have one 1987 save, but loading it does nothing. Also restarting my game and loading the save does nothing.
