I've noticed since I've been playing this game which is a fun game but I notice when I buy rubies and I get the the extra things on the side like the patient's the fast scooter etc. are all those things on a timer bc they disappear before I get a chance to use them. If I don't use them right away they'll disappear I also noticed that in the mist of playing a game I would finish the stage but it would tell me that I didn't make enough money on no smiling face
