The entire management side of the game has been fucked for like, forever by now.I haven't been able to build anything in the workshop for several weeks, even though I have the funds for it.
There are quite a few things that are required, yet everything is still red and unavailable for some reason.
Probably because it's not used for anything but a few character/scenes unlocks from the first building levels, so there's hardly any incentive to look into it.
