Auto Plaza has been REFUND, it is now free and earned with Real Estate 1st completion (default speed is set to 3s).
Soul Idler Auto Plaza can be bought 5 times and cost 50k (it reduce Auto Plaza speed by 0.5s).
Real Estate challenge were unlocking too early (sorry i overestimated you ^^) the unlocking condition is now 250. If you are in the challenge you can always QUIT from the challenge screen, but it will be locked till 250 again.
Fixed a bug with Demons reproduction not resetting after Real Estate challenge.
