I made an account to say this. I’ve found at least one cause of the bug, at least for me. Your mileage may vary, and I haven’t found a “cure,” but hopefully this will help someone.
Thanks to everyone who posted on this thread, you helped me figure out what’s going on, at least for me.
I definitely had the bug, so I started a new character. After I did anything with the new character, like, use a new item, go to a new place, do a mission, etc, I went to a datapoint I knew would give out Quickhacks, scum saved, and tried to get Quickhacks. I can verify, that for me, after buying cyberware from the Ripperdoc Cassius Ryder in Watson Northside, I was no longer able to get quickhacks. I went to an earlier save and once again I could get Quickhacks from data points. He’s the Ripperdoc Wakako sends you to for the free smartlink tattoo. Though my new game hasn’t gotten to that part, I was in that neighborhood grabbing the plans for Buzzsaw and Psalm 11:6 and stopped in for some low level cyberware. So if the free smartlink tattoo is the cause, it isn’t the only cause. I bought a few items, so it may be that just one of those items causes the bug, or that you could buy the bugged cyberware from other ripperdocs, but I haven’t gotten around to sussing that out. Maybe just walking into Cassius Ryder’s shop causes the bug.
I’ll look into that further... but, probably after I beat Doom Eternal Anciant Gods Part II, or likelier, it beats me.
Hope this makes sense and helps out. Let me know if you found anything more, different, contradictory, etc.
