From that point the studies available decresced drastically... Has anyone experienced the same thing? I know this time around is slower, but even the AI ones are gone.

Their ai studies are up for me 24/7 now but they are difficult and take a while. And I don’t get the regular ones anymore.

I had those AI studies as well so it sucks they aren't as prevalent anymore
