What determines when new parts are available (aside from power providers, like solar, coal, gas, etc)? I have no idea. So far I've unlocked larger offices, but that's it.
I've been playing this periodically (checking like twice a day, at least) for a month or so now, but am I the only one with difficulty getting enough gold for Dread Knight in any kind of reasonable time? My total collected gold in this ascension is 835N, and that's not even a fraction of what's needed for the next character o_O It seems to me like there's a character or two missing between Frostleaf and Dread Knight.
The new restocking feature- it'd be great to have even just a simple explaination of how it actually works. I keep thinking I've got it working right, come back 10 minutes later, and half my fuel is dead and not restocking
