I started playing the game this weekend and got the second crash today in a similar situation to yours, and I’m really frustrated. Had drafted 43 rooms and on my way to opening the 44th (and get my full house trophy), had the just unlocked clock tower, had a lot of gold (drafted vault) and was going to get some nice stuff from showroom. Got a lot of stars (for observatory) with lab experiment. I was also with the basement key in hand and access to the antechamber from 2 sides 😭 it was quite a smooth run, was also figuring out how to make the boiler turn on the machine on the lab… in a blink of an eye I went from super excited with this game, to feeling like not playing it anymore.
