Surprise, surprise, another bug. I was just in game and my 18 hour buildings happened to come up for collection. I tapped on ‘Collect All’ as I usually do, the total amount collected flashed on screen in green as it normally does, and all the building timers reset as they normally do. However, unlike what normally happens, I didn’t collect a single dollar of the billions of game cash those buildings would have normally produced. It just vanished into the ether.
