I can't seem to see an answer in comments... when you use angels to buy the 10/50/50 items on the stand, does that increase the cost of the next upgrade? Or does the upgrade cost scale stay the same, yet you just have a few more items?
Since today (23 May), I can no longer swap items with those in my inventory. I could this morning, but cannot now. Could this have been broken as part of the update?
Can you explain what you mean by swap items? Items from where? What type of items?
