I cant find any information on this, but it seems like a new feature or an old bug that showed up again.
It seems that gigs no longer allow you to gain money from hacking every access point, you can now only hack one to get money, the rest will now have nothing other then quickhack parts and exp. The first point you hack in a building will now give cash and show you getting it, but the rest will no longer show you getting cash and you indeed dont get any if you check your balance after.
Currently ive tried two different saves and two different gigs so it doesnt seem to be save specific or location specific. ill have to check more gigs and saves later. due to issues ive had with games over the years corrupting all saves, i keep an absurd number of them from a large amount of saving. If this is a new feature it would have been great if we were informed of this as its such a big part of the game, i cant advance in the game until this is resolved one way or the other.
edit: Also im on PC and dont use any mods.
edit2: id make my own thread but since im new i cant.
