I've seen this on here before, but nobody paid any attention so I thought I'd post it again.
When you buy 50 of a building, it adds up the prices of the next 50 buildings and gives them to you at that total price. But when you sell 50 of a building, it takes the most recent building you bought and multiplies that by 50, instead of totaling the previous 50 buildings bought. This allows you to make huge profits by just buying then selling 50 buildings at a time.
Please fix this, it's very game-breaking for any game.
"Did you ever hear the Tragedy of Darth Plagueis the wise? I thought not. It's not a story the Jedi would tell you. It's a Sith legend. Darth Plagueis was a Dark Lord of the Sith, so powerful and so wise he could use the Force to influence the midichlorians to create life... He had such a knowledge of the dark side that he could even keep the ones he cared about from dying. The dark side of the Force is a pathway to many abilities some consider to be unnatural. He became so powerful... the only thing he was afraid of was losing his power, which eventually, of course, he did. Unfortunately, he taught his apprentice everything he knew, then his apprentice killed him in his sleep. It's ironic he could save others from death, but not himself." - Sheev Palpatine
