I did a Dollar Mint run the other day (middle elevator) with a friend and it did seem a bit harder than before. There were fewer 8/9, but we did come in on Floor 20 if I remember right.
Miss Pet Agree and I also noticed that the elevator was different. It almost looks bigger now, like 8 toons could fit. Everyone was in the Cash CFO, so we could test this out, has anyone else noticed a change in elevator size? Many will attest to the fact that I am nuts, so the bigger elevator could very well be a figment of my imagination!
